Rutgers Chemists Serve Nitro Ice Cream

You won’t find smoking ice cream at Dairy Queen.

But you can find it at the Busch Campus, where chemistry instructor Donald Siegel is giving a demonstration on the effects of  liquid nitrogen at the Engineering Open House .

Some of the ingredients are familiar: sugar, cream, half and half and flavoring. But when Siegel adds the nitrogen,  a cloud of vapor rises from the bowl, freezing the mix in less than a minute. Then, it’s ready to serve.

As a few drops of nitrogen spilled outside the bowl earlier today, Siegel reassured the crowd.

“It’s not going to hurt you,” he said.

“What if I touch it?” asked Elizabeth DeFazio, 13, a student at Smalley Middle School in Bound Brook.

“It will feel VERY cold,” answered Siegel.

Elizabeth touched it anyway. She also tried the ice cream.

Did it taste funny?


“It’s good,” she declared. “And vanilla is my favorite flavor.”

Students from Bound Brook enjoy nitro ice cream.
