Believe it or not, liquid nitrogen can make a tasty ice cream

We caught up with Trish Mick from the Telus Spark Science Centre, who showed us a neat way to give kids a science lesson.

She combined cream, milk, sugar and chocolate in a bowl and made some of the best ice cream we've ever had.

The secret ingredient?

Liquid nitrogen.

The frosty liquid boils at -196įC. When it's added to a sugary mixture thatís sitting at room temperature the cream starts to freeze, and the nitrogen evaporates away.

It only took about 10 minutes for the entire concoction to be ready to eat.

Mick says itís a fun and creative way to get kids excited about chemistry.

We agree. It's hard to top a science experiment that you can eat!
