For the record, I am not huge into food for art or kids activities, but with toddlers, you have extra things to consider so I bend the rules a bit.
I had put this dry pasta in the sensory bin for the kids and they had a great time dumping and pouring it and listening to the rainstick like sound. But after about a week, I could tell the next step was putting it in their mouth or stepping on them all over the floor, so I took it out and thought I would color them and use them for something else!
I just separated them into four bowls and poured some liquid watercolor in each one. This stuff is awesome, but if I didn’t have it, I would be using food coloring which would work great.
I just stirred it with a spoon until it was all covered.
Then I laid it out flat, in a single layer on some foil to dry for a couple hours, this is so it doesn’t stick to itself, or the foil- you could use plastic wrap or wax paper but not things like newspaper or paper towels.
Then I just tied one to the end of a piece of string and gave each child a bowl with a mix of the colors and let them bead with the colored pasta!
Giving it a new life, and I will still probably have some left over to add to another project!
