100 Days of Science-- #25 Color Changing Slime

My boys could not have been more thrilled when I mentioned that we were going to be making some slime that changed color this week. We have made lots of versions of slime before and it's always a huge hit with the boys. In order to make our slime I knew we'd need liquid starch, school glue, and to make it change color I ordered this thermochromatic pigment . With all our ingredients assembled, we set to work. In our "science experiment bowl" (yes, we keep a cheap dollar store bowl set aside just for these types of things!) we mixed together equal parts glue and starch. We added 3 teaspoons of the pigment to give it a nice color. We talked about what thermochromatic meant and how it worked. Alec immediately told us that thermo was temperature like thermometer and I explained that chromatic meant color. So this meant our slime would change color based on temperature. 1/2 way through mixing and Evan decided we needed a photo since...
