Propane torch on Brown Shelf 4, Bin 1
At room temperature, the ball easily fits through the ring. Heating the ball in a flame causes it to expand and will not fit through the ring.

Propane Torch on Brown Shelf 4, Bin 1
Three (3) stainless steel tubes of OD 1.5", ID 1.25" with copper mesh placed about 1/5 the distance of the tube--the copper mesh is held in place by a piece of spring steel. The copper mesh is heated from the shorter end with a propane torch on a very low setting (be careful not to burn through the copper mesh). After a few seconds of heating, while holding the tube vertically, remove the heat source and you should hear the tube "singing."
The three lengths of tubes with their approximate frequencies are:
- 21 5/16" 350 Hz
- 17 7/16" 420 Hz
- 13 1/8" 560 Hz

Stirling engine producing mechanical motion from a difference of heat between top and bottom plates.
Directions from American Stirling Company:
Put about an inch of hot tap water in a coffee mug. Cover the mug with a paper plate and microwave the water until it is boiling vigorously. Be careful, boiling water is dangerous. Don't cover the mug with plastic wap, aluminm foil, or any tight fitting lid. When the water is finally boiling, remove the paper plate from the mug and place the engine on top. Wait thirty seconds, then flip the prop vigorously through in [the direction of the arrow indicated by the sticker]. ... the engine should start right up and run for several minutes.

Stirling engine producing mechanical motion from a difference of around 5 °C. Can be activated just by holding it in your hand, but recommended on cup of hot water.
Directions from 3B Scientific:
- Place the Stirling motor on the palm of your hand or a surface that is heated, e.g. on top of a cup of hot water.
- After about 1-2 minutes the base plate should have heated up sufficiently. On hot days, the temperature difference may not be great enough. If so, cool the top plate with a damp cloth.
- Spin the flywheel clockwise (looking towards the crankshaft).
- The Stirling motor rotates in an anti-clockwise direction when the top plate is heated, e.g. by sunlight or by a lamp. In this instance place the stirling motor on a cool surface such as a windowsill.
