Mad Scientist Monday

Today we tried to make our own mixture that would get the worms and raisins dancing.

Last week we used Sprite, this week we used baking soda and vinegar.

This time Mrs Aberhart cut the worms into 3.  We thought that they were too heavy last time and that is why they didn't go up and down.

First we put baking soda into water and then put the worms into that mixture.  We had to leave it soaking for 15 minutes.
Then we put the worms into the vinegar.  We got lots of bubble and fizzing, but our worms were still to heavy to go up and down.  The tail on one of Cassie and Briar's worms was moving.

So we decided to try it with the raisins.  Would they work?  We knew they worked with Sprite.  We repeated the process - soaking the raisins while we went to lunch and then after the break we put them in the vinegar.

Success!!!!  Our raisins were dancing in the vinegar.

You get lots of bubbles and fizzing when you mix the baking soda with the vinegar!
