I’m a Scientist is like school science lessons meet the X Factor! School students choose which scientist gets a prize of $1000 to communicate their work.
Scientists and students talk on this website. They both break down barriers, have fun and learn. But only the students get to vote.
This zone is the Disease Zone. It has scientists studying the causes and processes of illness . Who gets the prize? YOU decide!
No – that sound deliciously interesting!

Dear Ando; Yes, I did try. The marshmallows out of liquid nitrogen were very crisp, fragile and still sweet. It was demonstrated in one of science fair for children.
By the way, nitrogen is gas taking 79% of air at 1atm but turn to liquid at -196C.
It is without taste, without smell, without color and not toxic. However it could burn your skin if touched with bare hand, thus should be very careful.

I haven’t tried marshmallows frozen in liquid nitrogen, though it does sound rather cool. I have eaten ice cream made using liquid nitrogen though, which was very tasty! It’s a much faster way of making frozen desserts than just putting them in the freezer.
Your normal freezer, like the one you might have at home, is only around -20C, but liquid nitrogen is between -210C to -196C. This is very helpful in science, as we can freeze things instantly, which causes a lot less damage to things like cells than the slow process of freezing things in a normal freezer!

hahahaha, no. I think I would get fired from work if they saw me dip marshmellows in the liquid nitrogen and eat them.
But I’ll try one day if I get my hands on some liquid nitrogen after everybody has gone home…..
