Floating Scarves

As we entered the collaboratory, many of the Pine kids ran over to the wind tunnels asking if we could use it. They started putting the multicolored scarves through the tunnel, watching them gracefully float back down to the floor. 

"It's going out so high!"

"Look, I caught it!" 

E put several scarves through, watching each one hit the ground. He giggled as they floated high above their heads. 

L studied the second wind tunnel. She found a small white scarf and placed it on the fan used to propel the material. L put the scarf in and giggled with excitement as it started slowly rising to the top, but suddenly it stopped. L then began to shake the tube. 

L tried another scarf in hopes this one would come out the top. Still no luck. 

E & C wandered over to see what was happening. L continued to put scarves in, but they all magically hung in the hair. All three of the kids stared as the scarf stayed still. 

"Come out!"

L & C continued to try different scarves in the tunnel. 

How were the scarves just floating? What could they do to get them out?

"Let's shake it!"

"Oh man, it's coming back down."

L was both confused and frustrated then decided to use the other wind tunnel. She laughed as the scarves she put in came rushing out. B decided he would give it a try as well. 

The floating scarves were a mystery. "Why is it doing that?" (How did the float?) & "Why is it in there?"  (Why weren't they coming out?) were just a few of the questions that came up as the kids watched the scarves magically hang in the air.
