Can you blow up a balloon without your mouth? (Explanation)

How to blow up a balloon without your breath?

What you Need:

• 2 soda bottles
• 2 balloons
• 2 containers. 1 hot water, 1 cold water.
• An Adult or Tongs for hot water.

Preparation

1. Put one balloon on the Mouth of a bottle.
2. Repeat step 1 with the others.  
3. Get your water ready.
4. Get your parent on Standby or tongs right next to you.

How to do it

1. First put your one of your bottles in your cold water. Then the other in the hot water
2. Immerse the bottle in water and make sure that most of it is under.
3. Just sit and watch and see what happens to the two balloons. HINT After a while the balloon will go down because the water got cold.

What actually Happened???

All of the particles in the hotter bottle were whizzing around in the bottle and the hot air (That Rises) went into the balloon because the air has already taken up the room in the bottle.  While the other balloon was staying at the same rate as it was at the start because the water was cold.  It was in a state on an inertia while the other bottle was heating up.  As for the particles, after a while they will stop  and make the balloon go down because the water has gone cold and the air has come down from the balloon. From here you can tip out your water and pack up your experiment. 

Here is a Diagram on what happened.

Can you blow up a balloon without your mouth?

Can you blow up a Balloon without blowing the air in? Maybe. In this you will find the instructions to do it and you can do it yourself to see if this works.  Be careful, You may  need an adult to help you with some parts.

To start your experiment you will need some things. 2 Plastic Bottles (Coca Cola, Lemonade etc) 2 ordinary balloons, hot and cold water and an adult or tongs. For starters put the balloons on the bottles. On where the lid was. Prepare the water to hot water and cold water in separated containers. Once you have done this you can get your adult to help you put the bottle into the hot water. If you have tongs, just hold it around the neck and dunk it in. With the cold  water one you can  just put it in slightly. You do not need some tongs or an adult to help you with this part.

Once you have put the bottles in the water, you need to press the bottle right down into the water. Make sure the whole entire bottle is underwater. This is called immersing. You are Immersing the bottle in water. Why do you have to do this? So the hot air can heat up to bottle in water. That is why you have  to do this. The heat that the hot water has is going around the bottle that is heating the air that is in the bottle and that is what creates hot air. You still have to do the same with the cold water.

The next step is really easy. All you do is sit and wait. This is called observing. This is the scientific word for sitting and watching. As you observe. Have a look at the two different boxes. You might see one of them moving. Why is this. It is because the air is becoming hotter and thinking that it can escape through the balloon si the balloon is expanding and blowing up. As you Observe you might want to take some notes to see if there are any changes in your time of doing this.

Now I am going to explain what actually happened. As the air heated, all of the particles was whizzing around in the bottle and being heated up. Hot air rises, so the air would want to get out the balloon thinking that is the open world. As the balloon expands because the hot air is going in the balloon, blowing it up. But after a short while, The balloon will go down because the water will get to cold and the hot air will turn into the other bottle in the cold water. The particles will get cold as well and the other bottle. This is because the water in the container is colder that it was 30 minutes ago.

So, can a balloon blow up without blowing in to it. Yes you can. After a while it will go down by itself. This has proven that balloons will go up by itself with the right gear. I hoped you have been careful and if it did not work for you. Maybe you did it wrong.  

Down below there is a diagram that explains how it works:

Flexibility Test

On Monday. It was the first day of Term 4 and Mrs Roil thought that it was a good idea that we make a Flexibility Machine. We put our self's in groups of 5 and made our own machine. Yay it was time to test. I got 13 negative. Not to shabby for a boy like me. The other 4 people in my group got resealable results for them as well.

Over, Tuesday, Wednesday, Thursday and Friday we have being doing some Flexibility stretches to improve. Over those days we did over 20 stretches to improve. It Worked. We could feel  it with all of the muscles in our body's.  Our teacher was doing these for fitness and we improved.

It came the day that we were doing the test that we did on Monday was here. We needed to bet our score. I got negative 10. I improved 3 centimeters. Most of the class improved  but some dropped. We know that it worked because a boy in our class improved by 20 centimeters. It was really fun doing this and I want to do it again next week.

Egg Drop Experiment

On Thursday My class did an science experiment and we wanted to know if it works and why. Here is the details.

It worked because when you pull it quick it goes straight down into the water but if you go slowly  it will go down into the cup slow and break. The motion of the plate and the toilet roll that goes under the egg is the reason that the egg can go into the cup when it is pulled.  It could also become unsteady and smash on your plate if you pull it slowly. The force of Gravity will pull down the egg but because there is not the much gravity in water the egg will go slower and not break. It also has to do with the speed of the egg  as well as Gravity has force to do with speed.   


Here is some pictures.

Basic Optimist Sailing

If you are wondering about sailing over these school holidays this just might be the report for you. I’m going to tell all about Optimist Sailing and all of the basics you need to know in order to make this trip as memorable as you want it.

The very first thing that you need is a safety check. You need to make sure that you are wearing the right clothing like warm thermals and togs. Make sure that you have a life jacket on and good, hard shoes so your feet don't get glass in them. You will also need to make sure that your tiller and rudder are on properly and your sail is completely on the top pole and on the bottom pole. They need as tight as they can be. There are two bungs in the side’s and front of the boat. Make sure they are in tightly. If you have too much water in your boat there is a bucket at the front of the boat. Scoop the water out with it.

Once you have done the safety check make sure that your boat has been put together correctly. There needs to be a sail on the top pole. There needs to be 2 ropes hanging from it . On to hold it in place and the other to tighten and loosen the sail This is called the mainsheet rope. On the back there will the the rudder. The handle attached to the rudder is called  the tiller. On the sides there will be  two bungs. If there is any major water unplugged the bungees and you boat will not sink. If the water is  not so major you can use the bucket at the front.

Now this is the real deal. This is how to sail the boat. First of all you need to hop in the boat the correct way. If you have one person (Adult) in the boat they need to be lying down and be able to reach the mainsheet rope and the tiller. If you are a child just make sure that you are balancing the boat properly.  If you have two people in the boat. (One for each job) you both need to be sitting up if you are a child. Two adults can not fit. If you want to go faster pull on the rope to get  more wind in your sail and if you would like less speed loosen the rope. You always need to hold on to the rope so your sail doesn't fly away and the Boom will turn so make sure that you duck down so you don’t get a sore head. How to steer your boat is quite easy. If you would like to go left turn the tiller right and if you want to go right turn the tiller left. As easy as that. You will need some simple commands. To duck say Boom because some people get confused if you are pointing to a Duck. If you are at the front and you see something that you could hit say left or right to tell the other person to steer out of the way.

Capsizing can be a fun thing if done on purpose but when it comes out of nowhere it can be freaky. If you would like to capsize you need to lean to one side of the boat and take your centreboard out. Then you can tip. To recover capsizing you need to lean on on your centreboard and try to lean to the other side of boat. Also you need to have some hand signals. If none of these techniques has worked you need to yell “Help” and wave your hand so they see where you are and what they can do to rescue you. Once you are up right sail slowly back to shore or get someone to tow you back if anyone else is in the water with you.

My overall experience of yacht was very exciting and challenging because I have never done it before. I had a really great time and thought it was fun to try something I have never done before. My favorite part was going in around the buoy that they out out. You need the right regulation of speed to get through and around right. The water that you sail in can't be that choppy so Pandora Pond can be the best place to go Optimist Yachting because on a slightly windy day the water is fine and you can go in a yacht with no problems at all. My overall rating is 10/10 the boats didn’t have holes in them and you just cruise around the pond and enjoy the pond waters as you sail away from shore.

I hope this guide helped you plan your trip for Optimist Sailing. This activity can be fun and you can also learn how to even become a pro sailer by starting on these. They are also very good for kids to learn how to sail a boat or even the first time in a boat.  I hope this guide will help you to have the most memorable boating trip of your life.          

       

Yachting Reflection 2013

Yachting

Over the past week I have been Optimist Yachting and Kayaking. This is my reflection. Something I was pleased with was Yachting because I liked going round the sharp corners and flying round on the water. It was exciting because I have never been optimist yachting before and I thought it was really cool.

Something that I got scared about was going out far in the Kayak because I panicked a little and I couldn’t row left enough and I kept going the other direction. I got a little stressed with the kayak and I think I should go in a double next time so I won't get stuck and if I do the other person can come with me.

Something I need to improve is how to use a kayak oar properly and figuring out how to steer the kayak properly so I don’t go out where I was last time. That was freaky so that is my goal for next time.  

Something I could have done better was using the mainsheet the first time and not chicken out and sail back to shore and go back to the tiller prostitution  because I was too scared and made the rope very loose. I didn’t like it when the boat tipped when I was in control.

My plan next time I would like to go in a yacht by myself and be in charge so I can go by myself and I know when I want to steer and use the mainsheet so I know what to do it. I would also go on a single kayak so I can go at my own pace and not get a sore back anymore

Allround Day 1 (Monday)

It was really fun because it was my very first time in a yacht. I liked doing the tiller best and I went in a boat with Milly and in the kayak I was by myself and I got drifted out to sea.  It was terrible.  I liked rowing and sailing around the lake because it was fun and peaceful. I thought that this was really fun and I wanted to go again.

Allround Day 2 (Thursday)

Thursday was fun. We went yachting first and my buddy was Alex. She was a good buddy and I went on Mainsheet first and It was fun. Alex wanted to go on tiller and  I was fine with that.  It turned out that I was good at doing Mainsheet and I was just a (chicken thee first time.) For kayaking I was with Milly and we went under the bridge and around the harbour. It was fun. Milly took us around most of the harbour and I could just  sit back and relax. It was an amazing exprienice.  

Titanic Story

Back in 1912 when the Titanic was sailing along the voyage of New York, high winds were blowing which were making the boat go faster than it should be going and forcing it to fly at a whopping speed of 34 kilometers an hour. 1500 passengers onboard and flying at that speed meant a lot to slow down. People were yelling: “We have hit an Iceberg!” Lifeboats were traveling down the side to find another boat for help. “Help. Our boat hit an Iceberg” They all yelled as they were rowing away.

The next day the world woke up to the catastrophe of the unsinkable Titanic had sunk into an iceberg that popped out of the water by 1 meter while the boat was 14 meters in the air.  Heaps were saying that the boat that sunk was its sister Olympic but no one believed them.

People were going crazy when they heard their family members died. They discovered that the wind was blowing starboard and that is what blew it over into the water. The wind was blowing the boat fast and that was the catastrophe of the Titanic.
