As some examples, we use the retort stands for many purposes, but one of the most fun was during our Squashed Tomato Challenge (a Practical Action resource) at STEM Club. The idea is that the children are Nepalese tomato farmers, and their farms are at the top of a mountain. They must devise a way to transport their tomatoes to the market in the valley without squashing them. The children use the retort stands as the pylons to engineer their own cable car systems.
The stands have also been used in outreach with local Cub Packs to do a bit of chemistry, and to support drip bottles to recreate and observe wave patterns on a sandy beach with Year 3.
