No one volunteered so here's another from me

I made four goo bags. Each with food coloring and then one with salt, one with flour and water, one with water and oil, an one with oil and rice. I put packing tape over the zipper.

At first he ignored them but when I left them on the floor he went back over and explored on his own, smoothing, throwing, and rubbing them over his head. And also offering them o me and snatching them away when I held my hand out.... Stinker
