I had already tried to dye rice last year, but it was just not for me! Instead, I found this rice. Two bags was the perfect amount for these containers.
While I was looking for the rice, I stumbled across colored pasta! I only needed one bag of pasta for the bin.
I wanted my bins to be an independent activity, so I went with the shoebox sized Sterilite containers.
At first the bins simply had the rice or pasta, magnifying glasses and some tools for exploring: shovels, scoops, sifters and measuring cups.
