Homemade Hovercraft

This summer Trouble and I have been making vehicles that run on balloons. Our favorite balloon vehicle is this hovercraft my dad, Papa, told us about. He made this with his students when teaching about Newton's Laws.

What you need:

• spool
• old CD
• balloon
• glue (hot glue, crazy glue... whatever you have)

  What you do:
Put a little glue on the spool.

Glue the spool to the CD.

Stretch the balloon over the top of the spool.

Blow up the balloon by blowing into the hole in the CD.

Set the hovercraft down on a flat surface.
Give it a tap and watch it go.

Newton's laws may be quite complex 

but making this hovercraft was EASY!
