emily had to do a 6th grade science project and luckily she had just planned a camp fire lesson on scientific experiments so we used one of them for school. because it was a "science fair" format, there were endless amounts of hoops to jump through (abstract, hypothesis, research, raw data...results, conclusion... bibliography...) so from a 3 minute experiment, we had to fluff it up a whole lot.
supplies...
place coin on the plate, pour water... (this is called "coin rescue" by the way)
light paper on fire and put in glass jar...
put glass jar onto plate near coin (we had to move inside, wind malfunction)
listen to the squealing sound, watch the bubbles as a vacuum forms because of the combustion reaction (oxygen burned up and carbon dioxide produced)
soooo fun!
we tried food coloring too
coin rescued!
