Proud Mama

M was given an option, since she's in first grade, to participate in this year's science fair.

She loves anything dealing with science. I give the credit completely to Mad Science - we've been sending her to the after school program for about two years now and she LOVES it.

She decided to do something with Diet Coke and Mentos since she saw the Eepy Birds perform live at Maker Faire last year.

Her hypothesis: the fountains of cold and warm diet coke will be the same height when you add mentos to them.

We bought 7 liters of diet coke and a number of mentos (of course you have to have extra for sampling!)

I took three of them and put them in the oven at a very low heat. Another three were put in the fridge, and the last was kept at room temperature.

We took the temperature of the coke, added 4 mentos to it, and measured the fountain height.

Here's her science fair display.
She was so proud when she took to to school today. I was proud if her, too.

FWIW, the warm coke fountains were really higher than cold coke.
