At the recent Messy Fingers class we compared two different bubble solutions to find the very best one. But what makes for the best bubble solution?
Bubbles are an often blogged about subject around here. Check out some other entries on bubbles here and here.
Here's the give away part. I will have a small package of science goodies for winner of a random drawing. You can get one entry for each of the following:
1. Tell me what makes for the best bubble solution and how you would test it.
2. Follow this blog (just say you are in a separate comment).
3. Like the Millbury Public Library on Facebook (just say you are in a separate comment).
Deadline is Friday, April 5, 2013 at noon.
