Seems that sliced cheese (sliced from a block, not in wrappers) makes for a great adhesive. I found some toys ‘glued’ together today.
Seems like littleun appreciates how, when freshly sliced, the cheese is soft and pliant, but after time and exposure to air, it becomes firm enough to hold items together.
Megapoints for junior engineering skills but no more unsupervised snacking with the stuff 🙂
