Nicole started teaching 5-6th grade science this year, and we did a test run on an experiment at home tonight to make sure it would work. Apparently, acrylic beads are just the right density that is sinks in tap water and floats in water saturated with kosher salt. I have no idea why the experiment called for kosher salt, but it did and that's what we used. You can see nicely in exhibit A above, (the picture with the two cylinders), the left glass contains salt water and the acrylic ball floats, while it sinks in the tap water on the right. The picture above with the single glass shows the ball floating in the middle. I put the salt water in the bottom and gently poured the tap water in to keep them from mixing much. Just like oil and water, they stay separated enough for a while that the acrylic bead floats in the middle.
After our brief science experiment I found Daisy had ripped a hole in her favorite toy and was gutting it leaving that fluffy white stuff all over our living room. I was concerned it might be too late, but I took the chicken directly to the kitchen for an emergency repair with some 3-0 Nylon nonabsorbable sutures. I was able to repair the chicken's wounds, and within minutes the chicken was back being thrown wildly around. He will need some physical therapy for the first few days though.
Well, maybe we can keep finding some more science experiments to try and share. I want to test more stuff to see if it floats. David Letterman has a game called WIll it sink or will it float and it always amuses me. Does a can of peaches float? How about my cell phone? How about The Great Hunt by Robert Jordan? I think witches float.
