We started off with a bin on top of our light table and added some bubbles and liquid watercolor. The kids used straws to blow big bubbles in the solution. We also watched to see how the liquid watercolor moved in the container. We also experimented with smaller straws and bigger straws to see if the bubbles were different sizes.
I think they could have played with all of this for quite some time. They really had a blast with this activity. And the light table really added to the sensory experience of it all. Highly recommend this!!
