Thinking about children's toys has taught me about all of the different factors that go into making a toy. When I was younger I always wondered why some toys didn't exist, and realized that even though they seemed cool in my head, they probably didn't meet requirements for safety, cost, or the likelihood that a parent would actually buy it for their child. I also learned that toys teach children a lot about the way the world works and the way objects interact, even if they don't realize it.

When I was young, toys taught me a lot about how different objects interact with each other. Things like legos were able to withstand certain loads placed on them, until you exceeded the maximum stress allowed and the legos started to come apart. I learned about some of the common sense involved with friction through remote control cars and anything that slid. Physical forces could be seen in all types of toys that wouldn't normally be on such display, giving children a greater understanding of the natural laws that govern the world.
