I present to you… The Ice Hammer! Which is, of course, a hammer made of ice, and not a hammer made of something else that is mean to pound ice. That would be ridiculous, obviously.
I’m sure you’re wondering how I made this ice hammer. I shall tell you. Over at the Betty Brinn Children’s Museum there’s plenty of great stuff for kids. You might be young at heart, or just love hands-on science-type fun stuff, but as an adult you can’t really go to the museum without a child. Yeah, adult without a kid? You’re out of luck. The museum folks realized this wasn’t ideal, so they are starting a program called MakeShift which is an “adults only” thing at night, for adults interested in maker related activities.
I attended last night, and besides the provided food & (adult) drinks, we got to use a plasma cutter, play with a re-purposed/hacked pen plotter, see a trio of 3D printers spitting out plastic, and play around with other fun things. There was sewing and craft related stuff as well, and… oh yes, a vacuum former. You may have seen the hammer I made.
After we vacuum formed the hammer, I thought that it would make a nice mold for… something. Eventually I determined that it could hold water (well, after taping up a small crack caused by releasing the original hammer from the plastic sheet.)
I filled it with water, and carefully (uhhh) placed it in the freezer. And then wiped up all the water I spilled. Pro-tip: fill it with a cup while it’s in the freezer, or put it on something flat to transport it.
After freezing it was fairly easy to get it out of the plastic. I had thought I might have to let it melt a little, or add some warm water, but it came out in once piece.
I then made a second hammer, this time adding some food coloring to the water. The different colors didn’t really mix well, so I mixed them together, but I may do this again and let them stay separated from each other.
You can see the colored one broke. That happened when removing it from the plastic. Maybe I was a bit rougher on this one, or maybe the food coloring caused some strange weakness in the ice. (OR maybe I took it out too soon!) I’m not actually a scientist, but I welcome any ideas on the topic.
The next event is February 5th, 2015 and the topic is “Hot Stuff!” which could have something to do with Valentine’s Day, but I’ve heard rumors there will be soldering, hot glue, and drinks.
Keep an eye on the MakeShift page for upcoming events and other info… See ya there!
