Dr Ferrar strikes again!

You know we are in for fun when Dr Ferrar arrives wearing his lab coat and carrying a box of 'tricks'!  This time we were learning about 'dry ice' or frozen carbon dioxide.  We even got to hold (or juggle!) little pieces of it in our hands.  It was so cold...but it almost felt like it could burn us.  Strange!  Check out the fun we had in these pictures!  Ask us what was happening...

...and it all ended with a big bang when Dr Ferrar made a dry ice bomb - a very dangerous thing to do so as the Mythbusters say, "Don't try this at home!"  We stood well back and watched as a little bit of water and some dry ice created so much pressure in a Coke bottle that it exploded!
