Make a Balloon Rocket

The video explores a fun experiment with balloons to demonstrate the concept of forces. It begins with an introduction to the materials needed and a simple experiment of releasing air from a balloon to observe its movement. The video then guides viewers on how to build a balloon-powered rocket using string, a straw, and tape. It explains the science behind the movement, highlighting how forces work. Finally, it encourages viewers to experiment with different variables, such as the amount of air in the balloon, to see how it affects the rocket's performance.

What is needed to inflate a balloon?

• Water

• Air

• Helium

• Sand

What happens to a balloon when the air is released?

• It stays still

• It flies around

• It explodes

• It sinks immediately

Why does a balloon move in the opposite direction when air is released?

• Due to friction

• Because of magnetism

• Due to the force of air pushing it

• Because of gravity

What materials are needed to make a balloon-powered rocket?

• Plastic, rubber band, balloon

• Paper, glue, scissors, balloon

• Wood, nails, hammer, balloon

• String, straw, tape, balloon

What can you change to see different results in your balloon-powered rocket?

• The size of the straw

• The color of the balloon

• The type of string used

• The amount of air in the balloon
