Elmer's Color Rush Slime Kit, Includes Liquid Glue, Activator, Makes Color Changing, Glow in The Dark, Butter Slime and More, 10 Piece Kit - Perfect for Birthday Parties, Gift Idea, Kids Activity

What a great birthday idea! You've got a couple of choices. If you want ingredients, like glue, activator, etc, Sloomoo Institute has some kits for sale. They've got an "expert" kit that would be suitable fora group of adults I think, or a variety of smaller kits. If you're looking for slime that's already made and you just build and mix it, Slime Community has these baking kits that are really fun. You get things like apple pie, banana split or pizza you can "make." They're actually really fun - they come with a container of slime, clay, rolling pins for rolling out "dough," eggs, sugar, etc -- all made from slime. They're a little pricey, but you end up with a ton of slime after it's all mixed. You can buy glue and a box of borax for activator and make your own "kit" if you'd prefer to be able to customize it more (and it's a lot cheaper). Glue like Elmer's or Amazon are good. You can get clay & other fun add-ins from Amazon. Elmer's makes a bunch of different kits like this one or this one. BUT, it's much cheaper to buy the glue & borax separately. Whichever you choose, I'm sure it will be so much fun! Let us know if you want more details about buying the glue & activator separately and we can get you more info if needed.
