橡皮糖熊之死(1)

Hi, I'm Jessica And I'm going to be talking about a chemical demonstration today that I like

to call death of a gummy bear We eat these little guys all the time

and our bodies break down the sugar in a series of chemical reactions but what happens when you break down the sugar in

a gummy bear outside of our bodies? Well, MIT's Dr. John Dolhun is going to show us

Here he is at the Cambridge Science Festival at MIT Now, I'm going to actually be combusting a gummy candy

and my wife said, please don't tell them it's a bear Guess what? It's a bear

and I'm going to eat one right now and I'm eating a gummy candy

It's sugar and I'm going to chew on it and eat it

and what do you think that's going to happen to it? It's going to break down into carbon dioxide

Tomorrow I'm going to be breathing out CO2 I'm going to be perspiring. Water's going to be coming out
