Ivory Soap Clouds

fuzzy picture, but put bar of ivory soap in microwave...we put a paper towel under it so the soap would not be on the same placement as food might sometimes be...
 
 
somewhat hard to see, but beginning to heat up in microwave...
 
 
 
 
 
it has a slightly burned spot on each side of the original bar...notice how it is turned on its side now and it was lain flat originally...
 
 
 
it had a slightly spongy texture to it...it almost felt like angel food cake consistency...
 
 
it did have a air pocket inside of it when we broke it open. we discussed how heat causes chemical changes. we discussed air pockets and air escaping durign heat exchange. we discussed how it expanded and it changed the physical properties of the soap during the chemical change. 
 
for the sections that still felt slightly soapy, the child used it when he took a shower to see if it still worked as soap. it did not.  it fell apart and disintegrated in the shower.
