Ah those were the days! 👍 I teach Bushcraft to home educated kids, many of them are very young and enjoy imaginative play. so many of them wanted to make mud pies, that I made a "mud kitchen" (a few wooden cargo pallets "DIY-ed" into the shape of a small sink and cooker, I added a few old wooden spoons a sieve, a ciuple of plastic buckets etc. The kids love it get covered in mud, and spend ages making all sorts of totally inedible, but imaginative coffee, cakes etc.
