Cohesion

 This is a drop of water on a piece of wax paper...
 This is Kai, seeing what happens when he tries to move the drop of water with a toothpick..
 and Lacie is doing the same thing...

 as is Kathryn and Jayden...
 and Kenneth...
 and Aarin...
 and Breanna with a little help from Kayla, one of our HSU students...

What Room 5 found was that the water drop stuck to the toothpick and moved around the wax paper! 
Another experiment Room 5 did used a straw.  They dipped the straw into the water, put a finger over the end, lifted it out slightly, and observed what the water inside the straw looked like.
 Some of Room 5 were down at eye-level with the straw to get a good look! 
 What did they discover?  The water dipped down in the center...or was higher on the sides.  Why????
 What made it do this? 

 This would be a great question to ask your Room 5er!  I could write it here, but then it would be a 'spoiler'...
There are definitely some great discoveries to make about water!  Something we thought nothing about...plain ole water...is amazing!
