This is hands-down the most clever piece of toy design I’ve come across in quite a while. The Dutch designed Toideloi Stackhouse is a modular dollhouse for boys and girls - slot the wooden pieces together to build a house, sky-scraper, village or castle - something different every day. Made of Baltic Birch plywood the walls of the rooms simply slide together. No screws or tools required.
EYFS DINOSAUR TOPIC: Children can help to "hatch open" the dinosaur egg using salt and tools, revealing small dino toys. Made by simply putting toy inside balloon, fill with water, freeze overnight then cut balloon away.
