Flutter Effect is a self-feeding mechanism in which aerodynamic forces on a object (This case an airplane wing) are coupled with the natural mode of vibration of this object to produce a periodic and, sometimes, destructive motion.

This video shows a pumpkins cannon. It uses compressed air to accelerates the pumpkins through out a long pipe. As bigger the pipe, more time the pumpkin is accelerated, so higher is the inicial velocity. At a 45 degress angle the pumpkin reach the maximum horizontal distance.
Lets pump...pumpkins

This tick uses the pascal principle to break up the bottom of a bottle! You'll need some practice to do that. Warning, the broken glass can be very dangerous!
This video shows how to make ferrofluid using household materials

This video shows how to make hot ice, a supper saturated solution of sodium acittate that crystallizes when you disturb it or add a small crystal.
