Newton's first law of motion describes that every action has an equal and opposite reaction. We taped a balloon to a straw that was on a smooth piece of string. Be blew up the balloon and let go. The pressured air pushes the balloons along the string. We found out that if the balloon was smaller it was more aerodynamic and was faster along the string. If the balloon was trying to go up on an incline gravity would hold it back and it would just fall back down. Some of the balloons didn't even move. They just went a small distance then spun around the string.
To do this experiment you will need:
A Balloon.
A piece of smooth string, around 2m long.
Half a straw
Some tape
Hello Toby, I like how you tell the Reader what you need for the experiment and have pictures and videos so People can see what happen, Thought you did list the items maybe you could have said how to do the experiment in more detail, you do a very good job.
