A DIY project…

Free. Pick up near Warden/Danforth. Plastic kids play buckets. Purchased for an outdoor classroom. However, the buckets are now firmly stuck together as shown in the stacks in the photo. I can’t get them apart. And if you can get them apart, then you would want to avoid stacking them again, so they didn’t get stuck again. I imagined altering them in some way so they couldn’t get stuck, like a block glued inside so they don’t sit so deep when stacked, or a hole in the bottom to push a stick through to separate them? But I’ve had them like this in my house for a year and I’m just not going to take on this project! Maybe someone else wants to try?
