Interesting Green Stuff, Pt. 2

My previous post about the shamrock shakes happened last Thursday.  Friday morning I didn't have to be at work until later so it was the perfect day to knock out a science experiment I had been wanting to get done.  Starting work even 2 hrs later can be huge to a home-school mom who also works full-time outside the home.  So I wanted to do a color mixing experiment.  Unbeknownst to me, DD (age 5) already knew that blue & yellow make green but she still thought it was cool.  It was entertaining for DS (age 2) as well. 

Step 1.  Fill 2 cups with water.  Put blue food coloring in one and yellow food coloring (which, incidentally looks red in the bottle) in another.

Step 2.  We took 2 smaller paper towels and folded them in half.  One went from the blue cup to an empty cup in the middle and one went from the yellow cup to the same empty cup in the middle.

Step 3.  Wait

Once you have waited awhile you should have a pretty green cup in the middle.  However, when conducting this experiment with a 2-year-old in the house, please be warned that it will still work but it may not be pretty.

The medicine cups, etc in front of the glasses were what he decided to play with (ie. get water out of the glasses, try to drink it when Mom wasn't watching).  The green blob shows what happens when the same 2-year-old gets a hold of the blue food coloring that Mom really thought she had put back in the upper cupboard - not pretty but yes, blue and yellow do make green!

I did not get an ending picture but eventually the water and more color did make it's way into the middle glass.
