Thank you for the speedy response! I wanted to add that I didn’t have Kool-Aide on hand but I did have Jell-o which seemed to color the Oobleck nicely but the scent faded pretty quickly (next time I will use more). We also added sprinkles (the tiny round ones) to see what the colors would do. The sprinkles didn’t last long but it was fun to watch.

Yay, Patty! I’m so glad you are! Yes, there is definitely a shelf life to anything cornstarch and water based, as after a little while it starts to smell badly. Depending on your climate, I’d say you’d get at least 2 or 3 days of play out of a batch of oobleck. Just keep it covered in a cool place, and expect it to settle a little bit over night. To “bring it back to life”, get in there with your hands and mix it up, adding a little bit of extra water if needed. ENJOY!

Hmmm… I’ve never had that happen! That being said, I do find that red food colouring is the worst for staining, and in order to make even a dark pink colour, you need quite a lot. I’d try a different colour next time and see how it goes. :) And as for the mess – I know exactly what you mean. A happy, engaged munchkin makes it all worth it, doesn’t it?
