Science Trekkers at the Houghton County Fair

We're in Houghton at the county fair this weekend. Typically we don't head in this direction until Friday night, but this year, we opted to come for the whole fair! We will be running the Kid's Day activities on Saturday, and tonight..... we went to the Science Trekkers Tent! IT WAS SO COOL!

We had the opportunity to run across oobleck, stand inside giant bubbles...... and oh so much more!
Dane's favorite experiment involved jabbing a skewer through a balloon and NOT popping it. We also had "dragon breath" when we tried extremely cold graham crackers (frozen with liquid nitrogen). We watched as they blew up a garbage can, and put out a candle flame with an "invisible" gas.

You can learn more about some of the activities that were provided here: family engineering.

What Would You Do With It? Wednesday #4, Cardboard Tubes (Toilet Paper, Paper Towel, etc)

Welcome to this week's edition of What Would You Do With It? Wednesday. This week's item(s) are paper tubes. You most often find them at the end of a roll of toilet paper or paper toweling. I'm having trouble hunting up the photos I was going to post for this, so when I find them, I will add them. We have made: rain sticks kaleidoscopes marble runs and we have also cut the tubes and made them into flowers or snowflakes like these. If you would like to visit and link to some of our previous What Would You Do With It Wednesdays, please click here.

Making Moon Mud!

We usually make our moon sand with cornstarch , sand, and baby oil. However a blog reader commented that when they make their moon sand- they use water instead of oil. So, of course, my first thought was- why make moon sand when you could make MOON MUD? And so you have it- our homemade moon mud! Basically, it ends up being a sandy- runny oobleck! It acts kind of like a solid- and kind of like a liquid..... Now, I'm sure I will get all kinds of questions on the exact recipe and proportions to make this stuff..... The truth is, we rarely measure. We just mix it up until it looks and feels about right! Today, we made ours with too much water. (It was an experiment.) So, we removed some off the top. After we were done playing in the mud- we let it sit. A little bit more of the water evaporated while we napped.... Then, this afternoon- It was perfect! Hard as a rock on the bottom, until you dig into grab it... Then....
