Dissolvable Packing Peanuts: These make the most amazing pops when put into slime. The sizzle pop sounds are sooooooo satisfying, great for anyone who loves popping slime. You get 3 cram full cups worth of peanuts. They do dissolve after a while and become part of the slime. Just add a few more! Large Square Foam pieces: These are just like the large round foam beads many people add to their slime, but these are square! They creat an entire ly new texture and great bubble pops. Doesn't disolve and they don't brake up.
