Nice blog. I made a simple hovercraft for my 4 year old son this weekend with plywood a leaf blower and shower curtain. He learned about air pressure. Cool stuff! We found a fun site with neat science experiments like simple hovercraft directions. I will put the link below for anyone interested.

I love the mentos and coke experiment. I did it with my 4 year old son this weekend. He learned about chemical reactions and what a volcano looks like when it erupts. Cool stuff! We found another fun site with neat science experiments like this. I will put the link below for anyone interested.
