Thanks to Lynn and Mark's science kit, Seb has been dabbling in beakers and test results.
Yesterday Seb did the baking soda / vinegar
(lava for the volcano at your grade school science fair).
The results were great…especially the first attempt which went undocumented.
I was in the pantry getting the food coloring, when I heard a boom.
I came out to find our kitchen curtains covered in foam.
The cap had been put on while the reaction was taking place and the pressure was so intense it blew the screw lid right off.
LUCKILY, no one was hurt, no windows were broken
and the food coloring had not yet been added or the curtains as well as the rest of the kitchen would have been a mess!
The second experiment was mixing corn starch with water.
Had the amazing effect to be hard as a brick when trying to pick it up
and runny as water when not under pressure.
Fun stuff!
