I've always been fascinated by anything science related and my husband is the same way. So it's not too surprising that our children love to learn about science too. On our recent vacation we went to a science center which was a blast! We've been before but they had a bunch of new exhibits and more hands on activities. It was great! One thing we did this time that I don't think we did on our last trip was use this machine to weld pieces of metal together. No welding cable needed, just metal and heat. The girls really thought it was cool that the machine could heat up so quickly and get hot so fast within just seconds. They each got to take away little pieces of metal that were welded together. Pretty neat! The whole center is fantastic and I love how hands on it is. We'll definitely go again!
