With all the fun of MRI month in March, we failed to properly recognize the good doctor's birthday on March 2nd. The kids knew and begged most of the month to make our traditional birthday oobleck. By the end of the month, I finally obliged. This time we got a neighbor to come over and join in the fun.
Just an FYI, I did four boxes of cornstarch total and put one in each tub with some neon food coloring.
