Tips for the Best UV Slime Experience
🧴 Use the right glue: Make sure you're using the actual Elmer’s UV color-changing glue it’s the secret ingredient that makes the magic happen. I don't say that to be picky, but because there isn't a great alternative out there yet. ☀️ Test it indoors and outdoors: Let kids guess what color it might change to before heading outside!
🧼 Slime too sticky? Add a tiny bit more contact solution and knead it well. It'll come together with a little patience. 🧪 Bonus tip: Use this moment to talk about how UV light is invisible to the naked eye but still affects things around us, like this slime!
Storing Your Color Changing Slime
Once you’re done playing (and wow-ing your neighbors), store your UV slime in a resealable baggie or airtight container. It should last a few days of fun if kept sealed!
