How to Make Putty Slime
Equipment:
Instructions:
Step 1: Find what you need
- Gather your supplies and materials.
Step 2: Mix the first ingredients
- Pour 1/4 cup of white glue into a bowl.
- Add 1/2 teaspoon of baking soda.
- Stir together to mix the ingredients well, removing any clumps.
- Add 5 drops of food colouring, in the colour of your choice, and stir to combine.
Step 3: Activate the slime
- To activate the slime, pour in 1-1/2 teaspoons contact lens solution.
- Stir the slime until you can’t anymore and it pulls away from the bowl.
Step 4: Finish the slime
- Pick up the slime from the bowl and stretch/knead it in your hands. It shouldn’t be sticky once you’ve worked it long enough.If it’s still a bit sticky, add a few more drops of contact solution at a time.
- Set the slime down and add 1 teaspoon of cornstarch.
- Mix the slime and cornstarch with your hands.
- Add another teaspoon of cornstarch into the slime.
- Squish together and mix until you can’t see any white. Your slime should be thicker than before, and nice and squishy.If you want it even thicker, add a bit more cornstarch 1/4 teaspoon at a time.
- Your putty slime is complete!
Helpful Tips:
- Adjust the texture with cornstarch: Add less cornstarch for a slime that’s thick but still goopy and super stretchy. Add more cornstarch if you want a firmer, more moldable dough-like slime.
- Check your contact lens solution: Make sure it contains boric acid and sodium borate — these are the key ingredients that will activate and thicken your slime.
What makes this slime recipe “putty slime”?
Putty slime is thicker and squishier than regular slime. It has a bit of resistance to stretching, like putty, but still oozes and flows like slime. The texture is super soft and fun to play with!
How can I colour my putty slime?
Food colouring is the easiest way to add colour, but you can also use liquid watercolour paint, acrylic paint, or mica powder. Glitter is another fun option for sparkle — just keep in mind it shows up best in clear glue slimes.
Can I use actual putty to make slime?
Yes! You can soften putty into a more slime-like texture by mixing in hand cream, one little dot (about 1/8 teaspoon) at a time. Add slowly until the putty becomes more soft and stretchy, like slime.
Just don’t overdo it! Too much hand cream will “melt” the putty and make it sticky.
Putty slime really is the perfect mix of oozy slime fun and squishy putty satisfaction. With just glue, cornstarch, and a few simple add-ins, you can create a soft and stretchy slime that’s endlessly fun to squish, pull, and play with.
Whether you’re making it for stress relief, a rainy day activity, or simply for the love of slime, this recipe is sure to become a favourite go-to!
