Science experiments

We had a messy fun time yesterday with a "guest student".  The kids have been excited to try this non-Newtonian fluid experiment also know as oobleck .  What fun is all I can say! 

This experiment really blew everyone away, I have to admit it was pretty darned cool.  You can see it here in the pictures just dribbling from Corey's hands like slime.  However if you ball it up in your hands or tap on it with your fingers it's solid...very strange and cool.

love the face you can "see" him saying "Cool"

 This entertained the kids for a great deal of time and was sooo easy to make, it's nothing but cornstarch and water!  It is pretty messy for sure, but worth the clean up.  I love that they learned so much while having so much fun.  Our friend Theona was thrilled to participate with the big kids and really enjoyed the tactile portion of just feeling the goop in her hands. 

 Of course the girls adding some food coloring just to spice things up a bit.  I found this great natural food coloring called India Tree last year.  It's made from concentrated veggie colors.  The colors are wonderful for icing and cookies etc.  My one complaint with these is that they expired quickly.  I understand it's because they are not full of all kinds of chemical preservatives.  But, they were quite expensive and I only decorate baked products every so often.  We did of course use past the date on the box and never had a problem.  I guess this just means I need to figure out how to use the veggies directly to color in the future...hmmmmm....another science experiment?

In the end it was a fun afternoon well worth the mess and I'm sure they will want to make it again.  I however will be looking for more fun and messy science to try.
