I'll start by saying that I haven't mixed everything together yet because I felt how the white "yogurt" slime felt by itself and instantly fell in love. It's soooo stretchy and squishy with the best light strawberry vanilla scent. It inflates in size so much but does go back down if you stop playing with it for a little bit. It isn't sticky or stiff. It's one of my favorites to relax with right now just stretching and pulling it and squishing it between my fingers.
