In this Kate's Corner, we are going to make a balloon rocket.
All you need is a few simple things. First is a balloon blown up but not tied. You'll also need a straw, some tape, and string. We didn't have andy string so we just used some floss. Tie your string around chairs, a door knob, anything but just make sure it is tight and even. Tape your balloon to the straw and pull it to one side of your string. That will be your launch point. Time to let your balloon go and watch it shoot off.
So, what makes the balloon shoot off like a rocket? Well, as the air rushes out of the balloon, it creates a forward motion called thrust. Thrust is a pushing force created by the energy of the balloon forcing the air out. In real life rocket, thrust is created by the force of burning rocket fuel as it blasts from the rocket engine.
