3. Outdoor Baby Cages
The best way to give your kid with the daily dose of fresh air is by taking them outdoors. How about building an outdoor cage? These outdoor cages were a common fashion amongst British families in the early 19th century. This might look very crazy in today’s world but it was a great innovation then. While the mothers used to do all the household chores, the babies used to be locked in the cages to take in some fresh air and look around.
4. Radioactive Toys
There was a time when smoking was not considered unhealthy and doctors used to recommend it and so radiation-emitting substances weren’t considered life-threatening either. The atomic toy as shown in the picture in a mini-laboratory was common. These contained substances like polonium and uranium which are highly harmful radioactive substances and now are used in nuclear weapons.
