====== Fan Cart ======
{{:physicsdemos:mechanics:newtons_laws:fan_cart.jpg?600|}}

A small cart is driven by a battery-powered fan. When a magnetically-attached sail is installed in the path of the propelled air the cart ceases to move. 

===Setup===

Make sure batteries have charge and that you position the sail is in the path of the air (not the side where it sucks air).
