The objective of this box is to demonstrate the convection current around a heat source. The box isolates the airflow from the external environment. The heatsink is heated by the CPU emulator. It takes about 10 minutes to heat up the top of the heatsink to 60C. At this temperature the airflow is more dramatic.

Preliminary Design

Finished Product

A handle was made to increase mobility of this 10kg Plexiglas box. I believe this box can be useful in various demonstrations to demonstrate airflow.

Smoke can be introduced by a simple smoke generator (hot water + liquid Nitrogen)

A tube is connected to the side of the water bottle. The smoke is being created from mixing liquid nitrogen with hot water.

This is simply a bottle with liquid nitrogen vapor coming out on top. This is more idea because the airflow is smoother, unlike the first one where smoke shoots out.
