| 1 | Smashing Rose and Tube |
Properties of Materials at Low Temperatures
|
Pour LN2 into the beaker. Put the end of the rubber hose into the nitrogen. When the bubbling subsides, take it out and break it with a hammer. Put the flower or some lettuce into the liquid nitrogen. When frozen, crumble it with your hand. |

| 2 | Heating a Water Balloon |
Heat Transfer Applications
|
A balloon filled with water will not pop like a similar balloon filled with air. |
|
| 3 | Dropping Lead Shot |
Mechanical Equivalent of Heat
|
Stick the temperature probe (not thermometer!) into the bag of lead shot to find its initial temperature. Drop the bag from the height of 2 meters 10-20 times. Take the temperature of the lead again. The temp should rise 2-3 degrees Celsius. The specific heat of lead is 0.031 cal/(g C). The disc shows inverting a tube 10 times. |

| 4 | Boiling by Cooling |
Phase Changes: Liquid-Gas
|
Heat water to boiling in a Cincinnati flask. Remove heat, stopper and invert. Boiling continues again as ice is added to the dimple in the flask. |

| 5 | Drinking Bird |
Cooling by Evaporation
|
Soak the bird's head in the water and let him "drink". | Video |
