To make slime less sticky, you can try several effective methods:

• Knead the slime thoroughly. Sometimes sticky slime just needs more kneading to complete the chemical reaction and reduce stickiness. Letting it rest and then kneading again can help as well

• Add a small amount of activator. This includes contact lens solution (containing boric acid), borax solution, or laundry detergent. Add about 1/4 teaspoon at a time, kneading well after each addition, until the slime is less sticky. Be careful not to add too much, or the slime may become rubbery and lose stretchiness

• Use baking soda. Sprinkle 1/2 teaspoon baking soda into the slime and knead it in. Add more in small amounts if needed, but avoid overuse as it can reduce stretchiness

• Add baby oil. About 1 teaspoon of baby oil mixed into the slime can reduce stickiness and give it a shiny appearance. Avoid adding too much to prevent the slime from becoming too soft or goopy

• Clean your hands before playing. Sticky slime can sometimes be caused by dirty hands. Washing hands or using hand sanitizer before handling slime can reduce stickiness

• Add shaving cream for fluffy slime. If making fluffy slime, adding shaving cream and then activator can help achieve a non-sticky, fluffy texture

In summary, start by kneading the slime well, then add small amounts of activator (contact solution, borax, or detergent) or baking soda as needed. Baby oil can also help reduce stickiness. Always add these ingredients gradually to avoid making the slime too stiff or rubbery
