3/2/17- Spring Break STEM Activity

Spring break is right around the corner for many kids!  Not Jack, as he is in daycare/preschool (which doesn't close for spring break), and he basically just took a week off for a cold. So to preschool for him, and to work for Bobby and me. We'll take him on vacation in late summer/early fall, so don't feel too bad that he doesn't get spring break.

Since spring break is right around the corner, I thought now would be a good time to share another STEM activity.  The activity won't entertain your kids for a whole week (or maybe it could if they end up really liking it), but it is pretty fun.  The professional engineering society that I belong to did the activity at Chase Field's STEM Night, and then we recently did it at E-Day at the AZ Science Center. Not sure if the engineers or kids had more fun.

Without further ado, Galaxy Slime! The slime is so popular right now, check out the MSN video "Slime Fad is Back." I like to think our engineering society started the trend, but most likely we did not.

Supplies Needed:
1 cup Elmer's Glue (white or clear work)
1 cup Liquid Starch (we used the Walmart brand, Stay-Flo)
Food Coloring (optional)
Glitter (optional)
Plastic Bag (optional)

1) Put the glue into the bowl first.
2) Stir in food coloring and glitter, if desired.
3) Slowly stir in the liquid starch in increments.  You probably won't use the full cup of liquid starch.
4) Stir until you don't see the "white" liquid starch.  Then switch to kneading the slime with your hands, checking how stretchy the slime is.  If you want it stretchy vs.gak, again you probably won't use the full cup of liquid starch.
5) After your child is done playing with their slime, they can save it in a plastic bag (or Tupperware).

Jack's galaxy slime has lasted for a week after he made it at E-Day.  He liked mixing the colors and glitter in the glue, but he lost interest in the final product.  I do think this activity is fun to do with toddlers (who are past the put everything in their mouth stage), just remember toddlers are going to need more help with the food coloring than a 10 year old is (Jack squeezed like 100 drops in because I thought he could do it himself, haha).

It is great for ages 2-99. Thought I'd take the Lego approach there; after 99, you just won't find this activity or Legos fun. Oh, and it's called Galaxy Slime, because if you add color and glitter, it looks like a Galaxy!  Also, the glue and starch combine to make a polymer! Happy (STEM) Spring Break!
