Liquefaction of Carbon Dioxide - Part 1 of 4
The liquefaction of carbon dioxide is shown. In Part 1, dry ice is placed in a strong plastic tube and a pressure gauge is attached.

Liquefaction of Carbon Dioxide - Part 2 of 4
The liquefaction of carbon dioxide is shown. In Part 2, the valve is closed and the pressure in the tube builds until all three phases of carbon dioxide are present.
Ice Bomb
A cast iron bomb is completely filled with ice water, then placed into a dry-ice/acetone slush and covered with a wooden box. When the water in the bomb freezes, the cast iron bomb explodes, breaking into several pieces, and destroying the box in which it was placed.
Plastic Sulfur - Part 2 of 5
Solid sulfur is placed in a beaker and then heated in a bunsen burner flame. As the solid is heated, it begins to melt and a reddish brown liquid forms.
Plastic Sulfur - Part 3 of 5
As molten sulfur is heated to 180 degrees Celsius, the free-flowing liquid thickens and becomes very viscous.
Plastic Sulfur - Part 4 of 5
When viscous molten sulfur is heated to 200 degrees Celsius, more S-S bonds break and the sample is able to flow.
Plastic Sulfur - Part 5 of 5
The cooled sulfur has become a flexible plastic.
