Sticky, Slimy, Gooey (Family Science)

The second, and final, summer family science program was all about sticky, slimy, and gooey things. I read one book and then dived into the goop. 18 children participated.

My 4-year old received this book as a birthday gift. It is popular in my house, so I figured I would try to create some kind of storytime around it. My favorite illustration is the one with the frazzled art teacher sitting on the floor huffing into a paper bag.

Too Much Glue by Jason Lefebvre


1. Oobleck. The oldie, but goodie oobleck was our first activity. 2 parts corn starch to 1 part water. Food coloring optional. As families made (and played) with it, I explained what oobleck was and what they could do to make it act like both a solid and a liquid.

2. Gak. I tested this out last week at the final school-age science program. It was a hit then, and a definite hit this time as well. There are many recipes for it, but I mostly used the one from PBS:

4 oz white glue mixed with 4 oz water (pour water into empty glue bottle to get more glue out). Add food coloring. In a separate cup, mix 1 teaspoon Borax with 1/4 cup water (this is a modification from PBS, which calls for a 1/2 cup of water). Add 1 teaspoon of Borax solution to glue mixture (though you will ultimately need more than just a teaspoon), and mix with your fingers until it firms up.

I had the children pour the mixture onto sturdy paper plates to mix. They added small amounts of the Borax solution until all of it turned into a lump of gak.

3. Slime. This one came from Science Bob and is incredibly gross. Think of the saliva dripping from the alien’s mouth in any of the Alien movies, and you’ve pegged it (Slimer’s slime might also work). Very mucousy. The basic recipe is equal parts white glue, liquid starch, and water (I used 4 oz). Mix it together and prepare to be grossed out.
