I can still remember the oohs and ahhs from the elementary school students, even though I presented this program years ago. This special science program brought in a large group of day care participants and families, eager to jump at the chance to try out the interactive science stations around our activity room. The science program’s underwater success was a message in the bottle exercise. Children wrote a note in disappearing ink and placed the note in a bottle which they dunked in a bowl full of water in this first-hand look at the impact of water pressure. Of course, the clean-up required from the activity was a challenge, especially when one overly excited child decided to throw his bottle instead of gently dunking it, but this activity sure left a watery and wondrous impression. Science activities like this seem to draw out crowds at our library system, and this spring, our…
