If you're feeling pressure to do something fun, consider the vacuum cannon...

Air rushing into an evacuated tube pushes a ping-pong ball down the...
Ball drops from mast of PASCO cart; its motion can be considered relative to the moving cart or the track frame of reference.
Ball shot up from PASCO cart is caught by same; a puzzler to ponder if track is tilted and cart accelerates down (or decelerates up).
Which road is faster? A kinematics concept Puzzler.
Horizontal and vertical motions are independent of each other.
Two balls, starting with the same initial horizontal velocity, take two different paths: the one taking the high...
Glider acceleration by an inclined air track or by a falling weight/string attachment; large ballbearing rolling on PASCO track (with strings).
Time lapse image of a ping pong ball rolling down an inclined track. The bottom image has computer generated...

Standard meter sticks and selection of cubic volumes.
No temperature-controlled platinum rods here – just some sticks that are very close to a meter in length. Standard meter sticks as well as cubic centimeters and decimeters are...
Aluminum/Uranium and SF6/Air/Helium density comparisons.
The concept of mass per unit volume, aka density, is shown by having several different substances on hand for comparison. In solid materials, we have equal size chunks1 of aluminum (2...
Ball shot horizontally, one dropped vertically; both hit the ground at the same time.
The horizontal and vertical motions of a projectile are independent of each other. So two objects falling under the influence of gravity from the same...
