So, to start with, pour your glue into the bowl. More activator makes it less sticky, but also less stretchy and more rubbery - so it will fall apart too easily. But don't add a lot! Add only one drop at a time, kneading after each until you have the consistency that you want your slime to be. If it's still sticky after you knead it for about a minute, then you can add more activator.
You only need a couple drops!Įven if it looks sticky to you, just stick your hands in and start kneading it. Then add in a tiny bit of your activator. Next add shaving foam (add approximately the same amount of shaving foam as glue). Add a couple pinches of baking soda, ONLY if you're using contact lens (saline) solution as your activator.
The slime will end up being about twice the volume of the amount of glue you use (so use half as much glue as the amount of slime you want to end up with).
