Group Experiment #4

You knew it was coming!  There were two groups that chose vinegar and baking soda to mix together.  This is how the first experiment went:

Materials needed:  

• baking soda and vinegar
• funnel
• test tube
• straw

Procedure:

1. Funnel in the test tube.
2. Vinegar poured in until it fills halfway.
3. Pour baking soda for the other half of the tube.
4. Mix with a straw.

Predictions:  

• The powder will turn blue and into al liquid.  It won't be soft anymore.
• The blue won't be a squid anymore.
• It will turn dough-y.

Taking pictures was hard, so all I have are still shots captured from video.  I am sure you can imagine what it looked like!

"Its making bubbles!"

"Oh... my.... gosh."

"Ahhhhh!"

"It made a doughy thing at the bottom.  So one of my guesses is right!"

Keeping things quiet was going to be hard for this group.  I couldn't imagine how much these scientists wanted to share their findings!
