Fingerprint Recording and Diet Coke & mentos!

On Monday, November 8, 2010 the students of Einstein Club took their fingerprints using a couple of colorful stamp-pads and fingerprint record charts. Examining the different types fingerprints, we learned everything there is to know about identity and fingerprints.

We finished a little early - and since the girls were being such little angels (well most the time) – Aysha and I decided it would add some extra fun to our lesson if we went outside to do the ever-so-famous-and-truly-enthralling diet-coke and mentos experiment. It went great! We got to do it twice using the same bottle of coke and a half pack of mentos. The first time the coke shot out of the bottle in a fountain – almost soaking the spectators. The second time the bottle cap was totally off and the coke came gushing out for a couple seconds like a geyser. The ground was pretty much soaked with cola after we were through with the experiment.

Forensic science...
Lots mentos were threaded and dropped through a hole on the cap of coke, for the max effect.
Initiating the experiment.
Coke spraying out about half a meter into the air the first time the experiment was tried.
The coke gushing out all at once when the cap was taken off and more mentos thrown in for the second reaction.

GOO!

On November 1, 2010, the Einstein Class made goo! On April 12, 2011, we did it once again. This Einstein Club tradition has been around since the Club's dawn, and has, as ever been, a favorite. All it takes is equal amounts of borax and glue (both diluted in water) to be mixed in a plastic bag, until the texture turns slimy and gooey. The glue was mixed with the following food colorings so that the goo turned out the same color: red, blue and red and blue together (to make purple).
