Stretchy, a bit bouncy (not too slimy) and tons of fun to make and play with – this DIY rubber slime is sure to be a hit in your house.
This “recipe” is similar to what some are using for a homemade silly putty. I wouldn’t quite call this silly putty although it’s pretty similar. Silly Putty is more dense than this. I decided to name it Rubber Slime since that’s what it reminded us of.
You’ll need liquid starch, glue (a bit stronger formula than the classroom glue) and food coloring (optional).
Pour some glue into a bowl (this glass bowl I used was very easy to clean up) and add food coloring if you’re using it.
Mix it up well
and then add some liquid starch. Don’t use too much at first until you get a hang of the mixture. Here we have about 1 part glue to 1/2 – 3/4 parts starch
It will get hard to use a spoon or a stick so you’ll have to start using your hands
The mixture will start changing as the starch and glue mix together. Keep playing with it!
If your mixture starts to look like this but it still a bit sticky you can let it sit for a bit. It will change as you allow it to sit. Mix until it’s no longer sticky (doesn’t make a mess on your hands) and is the consistency you want. If it’s not quite right add a bit more glue or starch. When you’re adding either make sure you work it a bit and let it sit to mix in.
It’s very forgiving and there wasn’t a perfect mixture just add more glue/starch as needed to get the consistency you like best.
It can be stretched out
and if you have just the right amount of starch and it’s sat a bit you can even get it to bounce a bit when put into a ball shape.
We tried some different colors (mixing the glue and food coloring was fun)
If you get to this consitency let it sit for a few minute and it may be good for you. It’s not necessarily perfect right when you mix it.
See how it’s sticking just a bit? After it sat for a few minutes it was perfect. I assume that your climate might play a roll as well so do your own experimenting. It’s fun!
It may stick to and stay on some surfaces (like paper towels or fabric or carpet) so be careful. Since it doesn’t feel too sticky kids may be tempted to put it on things that it could stick to lol! Also the color may bleed onto some surfaces. For these it was ok on my white painted wood but left a stain on a poster board. (just giving you a heads up warning since it doesn’t seem as messy as some slime recipes)
A few minutes after the above picture was taken – gravity takes over a bit
So it’s sort of rubbery and slimy – hence our name Rubber Slime. Have fun and if you do it yourself let me know how you like it!
