For this experiment you will need:
Straw- longer than half your bottle,
One plastic bottle,
One balloon,
Water ( Just cold will do),
Food colouring (optional).
Hot glue gun,
Container- to contain the mess.
Method
Make sure you place down paper towels or newspaper to protect your surface.
Plug your hot glue gun into an outlet and let it heat up.
Grab your water bottle and cut a little hole where you'll be putting your straw in. (make sure the hole is 3/4 from the bottom).
Put the straw in the hole make sure it`s standing at an angle, then use hot glue to keep it in place. (make sure you put glue around the straw)
After the glue is done drying pour in your water.
Get your container and place it where the top of the straw is because that is where the water comes out.
After that place your balloon over the top of the bottle -this may take
3 people, then let go of it the balloon and watch the magic happen,
About the experiment:
So the air in the balloon is going down in the bottle which is forcing the water to go up and out of the straw, this happens by the air taking up space in the bottle which is why the water comes out of the straw.
Once the air has enough space it stops the water from coming out. By adding pressure to the balloon the water comes out faster. This is called acceleration.
