The other day I was surfing the web for a Christmas gift for my niece when I came across something called "Crayon Physics". Not everyone loves physics but who doesn’t love crayons? This is a great game with lots of potential and it is free you can pretend you are a kid again and play with your crayons! Some of the levels are a bit challenging – but it is a fun way to apply physics to this make believe world. Check it out: 

How cool is that? The only complaints I have (if you want to call them complaints) are; I wish it had more levels because I wanted to keep playing, and it only works on a PC

I think it will be a lot of fun playing this with my 5 year old niece – maybe she can teach me a few things
