Droplets of Liquid Nitrogen on Table Top

Droplets on liquid nitrogen on a table top will zip around like tiny hovercraft, suspended on a cushion of nitrogen gas from the rapidly evaporating droplet. The droplets of liquid may also oscillate and rotate rapidly. If placed on a dusty surface, they will pick up dust and carry it with them.

A good way to form large droplets with interesting motions is to dip a long strip of foam packing material into the liquid nitrogen. It will take up a considerable amount of the liquid, which can then be transferred to the table top in large droplets.

Droplets of Liquid Nitrogen on Table Top

Droplets on liquid nitrogen on a table top will zip around like tiny hovercraft, suspended on a cushion of nitrogen gas from the rapidly evaporating droplet. The droplets of liquid may also oscillate and rotate rapidly. If placed on a dusty surface, they will pick up dust and carry it with them.

Drops were often accompanied by a plume of condensed water vapor as they moved across the table top.
