Hovercrafts sighted in JCDS gym... all about friction

Science Mom explaining friction...  any questions??

How will the rug change how fast the car goes?


Riding on air... does it slide better?


Will it go faster or slower than on the rug?


Getting our hovercrafts ready to go!







Nice work, Yishai!


GREAT FUN!
