PLEASE REQUEST DEMOS WELL IN ADVANCE

Due to Physics Building renovations, the lead time to set up demo requests has increased due to the need to transport equipment across campus. Please be kind and let me know well ahead of time what you need.

Tornado Vortex

Procedure:

The carboy will be filled with water and corked at the bottom. After removing the cork, the carboy may have to be shaken around a bit before the vortex is formed. The water is replenished using the hose connected to the faucet allowing the vortex to last an indefinite period of time.

Hints:

For rooms without a sink, a two-liter bottle version can be used instead.

Equipment:

Large Plastic Carboy
