Easy DIY Rubber Slime

This looks like a fun activity to do with the kids, especially in these last days of summer. Similar to a homemade silly putty this is modified version of it that will allow the kids to bounce it as well. It is made with glue, liquid starch and of course, food coloring (the grosser the better).

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 and 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 Start mixing. 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 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)

So it’s sort of rubbery and slimy our name Rubber Slime. Have fun and if you do it yourself let me know how you like it!
