Lab-made Test Tubes

At my daughter’s science fair demo a few ages ago, the instructors requested her to include things like some mathematics evaluation tubes onto her behalf diagram.

“What do you believe?” They asked.

“I presume empty evaluation tubes could appear fine,” she said. The instructor shared with me that it was true – there are tons of test tubes on the market today, plus a number of them are really essay papers beautiful. However, how can you really know those to buy? You’ll find plenty of cases, however perhaps not the advice within this article apply to all of different kinds of evaluation tubes.

So I went into my daughter’s science fair materials lab to find a set of test tubes for her project. Of course, the lab doesn’t let you buy materials without buying them first, so Master Papers I had to go down to the materials room. I usually don’t go down there; I usually just wait for the other students who come out to run in and get something. But sometimes there’s a supply shortage, or other situations, and I need to get something done immediately. So I’m always tempted to go down to the materials lab, to see what’s available.

I walked in and met the lab teacher. He seemed like a friendly guy, but he was more interested in the students coming in for the supplies than in helping me find the right tubes. “I’ve been here for eight years, and I have to admit I’ve never seen anything like these,” he said, pointing to the hanging tubes on the wall. “They’re amazing! It’s crazy.”

I decided I wanted to make some types of tubes myself, since I knew that was going to be needed for my project, and since I could see that he was really into science. We talked about several types of tubes, and then he showed me some of the different materials that could be used to make those types of tubes. (He mentioned that plastic foam and compressed rubber can be used to make your own test tubes. If you buy them in bulk, they are surprisingly cheap!) I learned a lot about tubes-making from the teacher, and now I am able to show off a lot of the tubes he showed me.

First, I wanted to do some thinking about the type of test tube I would want. I realized that one of the major differences between a simple and complex tube is whether or not the center of the tube is of a different material from the side. In simpler cases, the side with a different color or texture is called the “contour”.

My next thought about test tubes was that I wanted to buy a set of test tubes, and then I would put the surface of each in a different container. Then I would make a bunch of tubes that had the same contour, but different side surfaces. By taking apart each of the tubes, I could then reassemble them and see what kind of look they gave off.

There is only one test tube in existence that I think comes close to that concept. That test tube is the Nautilus, by Buckyball. It’s one of the most popular toys at the moment, and I could have loved to own one, if I’d known about it. The thing is unusual in the sense that it has four different types of surfaces on the sides: the first surface is smooth, the second is a bit bumpy, the third has tiny bumps on the sides, and the fourth has bumps on the sides that are smooth. The thing is also different in the fact that it doesn’t use any plastic as its main material.

Of all the plastic I’ve seen used to make test tubes, Nautilus is the most interesting. They use the polystyrene, or PET, which is basically Styrofoam. They also use polyurethane as their main material, which is a somewhat less common material.

My next thought was about test tubes made of sand, or wood. Many people have used test tubes that are made out of wood, such as those found in biology labs. They are fairly traditional, and they look pretty cool.

I asked the teacher if he had ever thought about test tubes made of plastic, and polyurethane, and wood. He told me that he didn’t know of any of them, but he suggested that I talk to someone else in the department and get back to me. the next day.
