Table Cloth Pull
# 1F20.30

Description: A classic demonstration of the inertia of rest! A quick pull of the tablecloth and everything remains on the table.

Instructions: Lay out the table cloth and the dishes, etc. on top of it. Do not lay the dishes too close to the edge, as a little bit of motion should be expected. Leave some slack in the table cloth so your hands will come up to speed before the cloth becomes taut. Make sure that you pull straight back, and don't snap the table cloth like a whip. A rocking motion of your whole body will work better than just using your arms, and will make for a more visual presentation.

Hazards: Just a little embarrassment if your technique is lacking! ;)

Parts: Table cloth
Unbreakable dishes
A breakable flower vase
