Turning putty into slime is super fun and super easy. Start by heating up the putty in some hot water so it becomes softer and easier to stretch and pull. Then, mix in some hand lotion and hair conditioner to change the texture to a gooey, slimy consistency. Store your slime in an airtight container in your refrigerator for up to a week. That’s all there is to it!

Heating the Putty

  1. The bowl needs to be large enough to fully submerge the putty into the water. Heat the water until it’s hot but not boiling then pour it into the bowl and allow it to cool down enough so you can put your hands into it. [1]
    • Use a microwave-safe bowl and microwave the water for 1-2 minutes until it’s hot enough to steam but not boiling.
    • You could also use hot water from the tap if it gets hot enough to give off steam.
    • Wait about 2-3 minutes to allow the water to cool down.

    Warning! Hot water can burn your hands. Make sure the water is cool enough to touch without burning yourself. If you’re a kid, ask an adult for help, just to be safe.

    Take the putty in your hands and roll it around in your palms. Keep rolling it around until you’ve formed a nice round ball. [2]
    • Use putty intended for play, like silly putty, rather than caulking or home improvement putty.
    • Squish the ball flat a few times and then roll it back up so you can press out any air that might be trapped in it.

  3. Gently drop the putty into the water so it’s fully submerged. Wait a few seconds to let the outside of the ball heat up so it becomes soft and malleable. [3]
    • Make sure the water isn’t too hot or you could melt the putty into goo instead of slime! The water should be cool enough for you to touch, but still hot enough to give off steam.

    Spend about 10-15 more seconds stretching and pulling the putty apart in the water so it’s heated evenly. Squish the putty and pull it, but try not to separate it into multiple pieces. [4]
    • If the putty does break into pieces, pull it out of the water, squeeze the pieces together to reconnect them, then submerge it in the water again.
  5. When you take the putty out of the water, it will be loose and easy to stretch. Lie it down on a surface in front of you and flatten it out into a sheet. [5]
    • Use a plate to keep the putty contained and leave less of a mess.

  1. The lotion will loosen and moisten the putty to help change the texture.You don’t need a lot of lotion to change the texture of the putty. Place a dab of hand lotion in the center of the putty. [6]
    • Add about 1 teaspoon (4.9 mL) for every 1 ounce (28 g) of putty.
    • You can add a nice smell to the putty by choosing a fragrant lotion.
  2. Watermark wikiHow to Turn Putty Into Slime
    After you’ve added your dab of lotion to the putty, fold it over onto itself so the lotion is in the center. This will help you distribute the lotion into the putty without it running or squirting out. [7]
    • You can pinch the edges around the putty to keep the lotion contained in the center.
  3. Watermark wikiHow to Turn Putty Into Slime
    Take the putty in your hands and use the tips of your fingers to work and knead the putty. The putty will start to change texture and become slimy.
    • Stretch the putty and squish it back together while you’re kneading to really work the lotion into it.
    • If the putty doesn’t get softer after you’ve kneaded it and mixed in all of the lotion, add more lotion until it starts to loosen up and turn into slime.
  4. Watermark wikiHow to Turn Putty Into Slime
    To add an even more slimy texture to the putty, squirt a dab of hair conditioner onto it. Fold the slime over the conditioner so it’s in the center of it.
    • If you don’t have any hair conditioner, use hair gel instead to make the slime gooey.
  5. Watermark wikiHow to Turn Putty Into Slime
    Keep using your fingers to work the conditioner into the slime until it’s as gooey as you want it to be. Squish, squeeze, and pull the slime to mix the lotion and conditioner into it.
    • Add a little more conditioner if the putty hasn’t is still solid after you’ve mixed in the lotion and conditioner.

    Tip: If you want your slime to be even slimier, add more conditioner to it!

  6. Store the slime in an airtight container for up to a week. Your slime will eventually need to be disposed of, but you can make it last longer by storing it in the right container. Use a ziploc bag or an airtight container and keep the slime in your refrigerator. [8]
    • Check on the slime after a few days. Throw it away if there’s mold, lots of dirt, or an unpleasant odor coming from it.
    • Throw the slime away in a garbage can. Don’t flush it down the sink or it could clog the drain.

    You can use shampoo to soften the slime, and mix both lotion and shampoo together and add it to the slime.

    You have added too much lotion, hair gel or conditioner etc., try putting it into the fridge or freezer for a bit and see what happens. Next time, try to add less of what you added. You could also experiment different products and see which one is better for this recipe.

    What do you do if you've melted it?

    Community Answer
    Put it in the fridge for around ten to thirty minutes or more and try to knead it. If it it is too solid, let it sit in warm water for a maximum of 5 minutes and add a little bit of conditioner, shampoo, lotion or hair gel.
