We went to the toy store the other day to look for a “Wacky Zingo” stuffed toy that has a code which opens up an extra Webkinz game. They were sold out when we went there, but the kids had a good time looking around at the other stuff in the store. My son in particular was interested in the circuits lab stuff and the chemistry sets. I told him that I thought I had one at home and would show him when we got back from the store. Luckily, I DID have one at home that I had found at the thrift store and stashed for the day the kids would be ready for it. It cost $2 and had all the stuff inside. The one at the toy store was $25. It made for a nice side lesson in money matters for the boy. Anyway, we have been slowly looking through the manual and trying out the less messy stuff.
This morning, we tried out an experiment with filter paper and food coloring. Basically, you put a drop of green food coloring onto some filter paper and then rest it in a bit of water. Capillary action moves the water up the filter paper. We set it up using green coloring and then decided to add red and yellow also. We guessed that you might see blue and yellow on the paper that had the green sample because the manual asked what color would wind up on top after the dye was carried up the filter. We also guessed that the red and yellow ones wold just be red and yellow. Here it is in progress. We were right! The green actually separated into yellow, then green, then blue on top.
After we were done with the experiment, the kids used droppers to make beautiful coffee filters with more food coloring and water.
