Good Slime/Bad Slime

We tried two different mixtures of gak or slime yesterday. One was gross and messy and the other was great.  We've tried this once before with liquid starch and glue and it was a bit of a gooey disaster as well.  I didn't know it would be so difficult to get right.  This time we tried the following process:

Bowl 1: 1 cup warm water and a teaspoon of Borax
Bowl 2: 1/2 cup warm water and 8 oz. (or one bottle) of glue and food coloring
Combine and stir.  Pick up the gooey part and squish it as it becomes a polymer.  The water pretty much just gets left behind in the bowl.

Using Elmer's white school glue makes a great silly putty like substance.  Clear, discount school supply brand glue made a disgusting slime (the blue one) that made a huge mess but it was a great sensory experience that the girls highly enjoyed.  Maybe it turns out better with a different brand of glue?  It was gross.

Oh how fun and messy!

I'm a little confused--you were disappointed that the slime was gross?

I was hoping for something that would stick to itself more rather than to us. It was too liquidy and didn't hold together well.

I know what you mean :)

In the pictures the blue stuff looks totally slimy and then cleaner stuff looks like silly putty.

To repent for my sarcasm I did a little research and found a website where I learned more than I ever thought I would know about slime:

I also read that to get different consistencies you can add shaving cream or baby powder to the mixture and if you add glow in the dark paint the slime will glow in the dark.

I also found the following from a science teacher:

Slime not working?
If your slime is too sticky or runny, try adding more borax solution or starch. If your slime is too stringy, add more glue and work it in by kneading it in your hands. Sometimes you will have to add enough glue to get it back to the sticky stage, then add a drop or two of borax or starch to finish it up. Be careful not to add too much borax/starch or the slime may get stringy or crumble depending on the type of slime you are trying to make. It is best to add 1-2 drops at a time and work it in with your hands. If you are having trouble with the goobers, give them time to sit! Sometimes it takes a few minutes for goobers to gel. They won’t act like the other slimes, but should gel together to make a slimy ooze.
NOTE: If all else fails and you can’t get the goo to slime, pitch it and try a new batch! Sometimes you’ll get a bad batch and nothing will work to get it to slime stage.

Truthfully, the more I learn about slime the more it reminds me of making pie crusts...

difficult...

See you tomorrow!!
