  1. We recently had two large trays of goop at a combined birthday party for our 3 and 5 year old. All the children at the party were cousins ranging in age from 2-14. Every one of them loved the goop! We hid little plastic frogs in the goop and the fun had discovering them and trying to get them out was priceless. The goop was spread far and wide across our back deck but was easily cleaned up afterwards with the hose! So easy to prepare and so much fun:)

  2. I just love goop…not only do my twins love it their teenage sister has been known to have fun with it too! love those happy little faces in your pics!

  3. We were telling friends about the way corn flour and water act during a dinner at our place a while back. We decided to show them what we were talking about….and soon after there were a bunch of amazed adults having fun playing with cornflour slime. The kids lots interest in 5 mins but the adults kept playing. It was hillarious.
