I got this great idea from Kiddio, and my kids loved it.
The supplies are:
Shallow glass bowl
2/3 C water
1 T dish soap
First note!! Make sure you do not INHALE only EXHALE!!! Place water, soap, and food coloring in bowl. Blow into the straw and create bubbles. Place paper flat on top of bubbles and the bubbles popping will create cool artwork.
I think the best part of this activity was watching them blow bubbles through their straws. I always tell them at the dinner table that if they are going to use straws they can't blow bubbles. So, today they thought it was cool that they were able to do it and create art at the same time.
