Gabe is learning about mixing colors. So today with daddy he used our new test tubes and mixed color water. He was having so much fun. We gave him some droppers to get the water up and transfer to the other tubes. If you can see there is also color paddles on the table to that we got the other day. These paddles are great. They are translucent so when he puts one on top of another he can see the new color they make.
