Starters:
1)Falling tin can with holes in: Fill a tin can with water. Show how water comes out of the holes. Then drop it and show how the water no longer comes out of the holes as the water is falling at the same rate as the tin can.
2) Falling force meter: using a dial force meter (10N) attach a 1kg mass to the force meter and show that it reads 10N (a nice place to recap the wieght equation etc.). Then drop the force meter onto a cushion or sandbag a notice that the force meter reads 0N on the way down as the force meter is falling at the same rate as the mass. (could this be done with a PASCO force meter?). Possibly use some string and the loops in the ceiling to lift up the system and then drop it to keep people clear of the drop zone?
