Balloon in a Bottle

Balloon in a Bottle

Can you blow up a Balloon in a bottle? Is it possible. Maybe. In this experiment you will find how to do this.

Materials

1. 2 bottles
2. 2 balloons
3. 1 pin

What to do

1. First. Get a balloon inside 1 bottle and blow it up
2. Take the other bottle and put a hole in it with the pin. Just a small one
3. Noe do step 1 with the second bottle.
4. What Happened

What Happened????????

With the first bottle the balloon couldn’t work properly but the second one did because the air is been pushing. The big secret is that there is a hole in the bottom so the air is coming out. If you put your finger over the hole the balloon will stay up. This can work on any type of bottle just as long you have a hole in it.

ALWAYS HAVE ADULT SUPERVISION.    

Tragic

Tragic

Warning: This contains some Gross scenes.

It was a while ago (January 3rd 2011 to be precise) and there were 5 people biking along the Napier bike way. Their names were myself Ethin, my sister Sage, Justin my step brother and Mum and my step Dad Blair. We all just got new bikes for Christmas and we went to go try them out. We planned a 5 hour day of cycling excitement. We were going to bike down to Hot Chick for lunch.

It was a busy day and there were people everywhere. I was going to lead since I was the smallest. Everyone had to go at my pace. Justin hated it. Sage didn’t like biking so she wasn’t that bothered. Me and Mum always bike so I went fast. Justin and Sage didn’t see it coming. Sage was already puffing and  Blair didn’t know I was this good.

It was like a hurricane of people coming to me. I had to weave my way through them.  It was like I was making a bag out of wool and I was the needle. Suddenly, there was a lady the wasn’t looking anywhere  but back at her friend. BANG. She hit me. I was trapped in under my bike. I was screaming for help. I was in so much pain. Luckily, I was wearing a helmet. Blair pulled my bike off me. There was people going slow for me. The hurricane suddenly stopped. Mum walked me back to the car and Blair took Justin and Sage to bike down to the aquarium and bike back.  

Finally, we got back to the car and Mum had a proper look at my knee. It was oozing blood and plasma. “EWW”, screamed Mum. She put a plaster over it. That didn't do anything. The blood and plasma was oozing down my leg. Blair, Sage and Justin came back from their bike ride to the aquarium and they thought it was disgusting. Blair found a little cloth a wiped off all of the disgusting liquid. We waited for a little bit and then the liquid stopped pouring out.

So did you get the catastrophe? I fell off my bike and hurt myself. It was bad. Today I still have the scar on my right leg. The good thing was I was wearing a helmet like every cyclist should. I hope this changes your mind on how to cycle properly. Remember to wear a helmet at all times.  

The Force

The Force

Today at school. I did an experiment that makes a Ping pong ball float in the air. Why. In here it will tell you how to do the experiment and how it works.

What you will need: 

A Hairdryer

3 ping pong balls. 

How to do the experiment

1. Hold your hairdryer in midair turned on. It will need to be on a high setting. 
2. Put a ping pong ball on top of the hairdryer and it will float. 
3. If you will like to you can add on another ball and another

How and Why does it work. 

This works because the air that the dryer is making is pushing it up. Why cant it go high. The invisible force called Gravity is battling against the wind to pull it down. If you add another ball. They will bobble up and down and one of them will fall off. This is because the wind field if not wide enough to hold both balls inside its field. 

 

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.

Hot Water Cold Water
 

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.
