Description:

This can also be called expansion rod with straw.

Setup:

1. Install the burner gas tube with the gas source.
2. Make sure that you have the gas switch off and in the right pressure that you want before you turn it on.
3. Put the long rod on the woods by the two end of the rod.
4. On one end, put the lead brick on top of the rod. On another end, put the pin with the straw in between the rod and a wood block.

Cautions, Warnings, or Safety Concerns:

1. Beware of the heated rod.
2. You should use the high enough wood block that allows the straw to spin.

Demonstration:

This demonstration show the thermal expansion of the material. Once you put the lead brick on the one end of the rod that means it can hardly expand on the side. While you heat the rod by the burner, the rod is starting to extend to the other side. You will see the straw spinning while you heat the rod because the extension of the rod makes the pin spin forward. Due to this, it makes the straw spinning.
