today I'm going to show you how to build a hovercraft. This is very fun to make and very simple.
you will need:
A disc (a empty one nothing on it)
A water bottle cap
A balloon (any color)
One piece of tape
Step one put the tape covering the hole. Poke holes in the tape so the air goes out. Then glue the cap to the disc. Wait till it drys.
step two blow the balloon and twist it so the air does not go out.
happy flying. Be sure to vote for me on the launch it contest.
