My employer has sent me back to school to finish up my degree. I’ve been 8 credits from my AA for about a decade. One of the required classes I still needed was a lab, so I’m taking a biology lab….online…
Since it’s a lab, I get to do experiments at home, and experiments means test tubes. I ordered 10 on amazon, and needed something to hold them so they wouldn’t get broken. Thus, the test tube holder. Just some scraps out of the bin, about 20 minutes in the shop, and voila. Nothing fancy, but it gets the job done, and uses up some of those scraps.

The good news is, its a biology lab, so I shouldn’t blow the house up or anything. I remember in fourth grade, our teacher had us bring in store bought chemistry sets. My kit didn’t have the same chemical samples as everyone else, and instead of speaking up, I just tried mixing other things….I ended up causing a reaction that heated to the tube to the point that it burst, and the chemicals spilled onto the desk and charred the top. I haven’t done much chemistry since! Luckily no one was hurt.

Ellen – That is awesome! You’ve already repurposed this for when my class is over!

It reminds me the good old days of chemistry lab and the small of sulfur.

Make sure the tube is not red hot when you insert it there. It beats the plastic holder that came with chemistry set I bought for my son few years ago.

Well done.
