Science Saturday: Halloween Goo!

We had our last Science Saturday of 2013 the weekend before Halloween and decided it would be most fun to celebrate Halloween with Goo! Here's the original silly putty science post. This Science Saturday activity was a repeat of this Silly Putty Science Saturday from last year.

I encouraged friends to dress up in Halloween costumes and then realized that it was going to get messy. Luckily, I found these disposable aprons on Amazon (affiliate link). We only had one casualty, an adult sweater sleeve, but I think he got enough goo out and it was recoverable.

In honor of the Halloween spirit, here's my Capt. Hook and Smee before the festivities:

We had fun mixing glue, liquid starch, and colors to make our silly putty. I'm still surprised about how much little kids love mixing colors and telling you what the combination of colors make. We had green, purple, orange, and all of the primary colors represented.

Our friends also had fun examining the physical properties of silly putty. If you pull it really fast, it rips pretty cleanly:

If you pull it slowly:

You can make a jump rope!

Thanks to everyone who showed up and had fun! I'm hoping to find a community room/center, so we can start Science Saturday back up in January or February (to make up for the 1-2 mo I'll be out of commission in the spring).
