 Colander & Pipe Cleaners

Easy peasy activity found on Pinterest.

No mess, no set-up, and basically no need to buy any supplies if you have a couple pipe cleaners & a colander around.

 Engrossed!

It isn't an activity that buys mom or dad any time to get something else done, but for the ten minutes of play it provided, she was completely engrossed. She told me she was "making flowers."
