Super Science Friday Fun - Using Wind Hovercrafts

We made Hovercrafts.  The air flow created by the balloon causes a cushion of moving air between the disc and the surface. This lifts the CD and reduces the friction which allows the disc to hover freely. Large scale hovercraft are capable of traveling over land, snow and water.

After running our first trial we decided to make it slippery by using soap.  We thought this would make less friction.  But it actually made more friction and the CD got stuck!

Then we tried with more water on the table.  Our hovercraft went really fast.
