Kraftex Copper Tape [1/4" x108ft, 2PK] – Copper Foil Tape for Stained Glass, DIY Crafts, Guitar Shielding, Slug Control & Faraday Projects

This worked well for having my students make their own battery and diode bulb circuits

What a great value and price for these 2 huge rolls of copper foil tape. We just starting a stained-glass class and needed this to do our projects. We didn't want to invest a lot of money, so we were looking for quality and value. This tape definitely fit the bill. I couldn't be happier.

I was hesitant to order this given some of the reviews that said the adhesive is NOT conductive. Willing to try it anyway because those reviews appeared to be copy/paste reviews for other copper foil tape sellers. Seems to be something not quite on the up and up there. Anyway, as soon as I received the tape i grabbed a piece of scrap paper to see if this would work. I am going to introduce a group of kids to paper circuits. I cut a pice off the roll about 6" long, then ripped the pice in half to get 2 3" long pieces. I stuck one piece down to the scrap paper and layed the other lightly crossing over the first piece. I did not press the second piece down any harder than I had to. I wanted to make the worst physical contact between the 2 possible. I then measured the continuity between the 2 with a Fluke DVM. The 2 pieces were electrically connected. I have no doubt this tape will work well for our paper circuits project.

I used this to make snail barriers for my garden plants. Bought a roll of 8" wide galvanized sheeting, cut that down the middle to make 2 4" strips, and formed them into large circles to surround my tomato plants (pressing bottom edge into the soil).On each circle, I added a line of the copper foil about 1" below the upper edge, and another foil line about 1/4" below that one, so a snail crawling across those would encounter the edges of both. Checking for a voltage differential (like "tasting" a 9V battery), across the zinc/copper edges, gave a slight tingle which presumably would be noticed by a snail crossing those rows. And (as expected), stronger than doing the same thing using aluminum as a foundation.The snails didn't nibble my tomato plants, but I cannot be certain this was the reason. I'm happy with it, might test more thoroughly another year.

The media could not be loaded. It has adhesive on one side of the tape, and bare copper is exposed when you roll it up on a bolt shaft.The adhesive is thin enough that the thickness of the tape is similar to thin clear office tape.The bare copper has low static friction as shown in the video snippet.The thinness allows me to adjust the number of layers for a perfect bushing fitting.

Copper is a bit thin but the foil works well and the adhesion is excellent. The price is a bargain.

Used this to review series and parallel circuits with 7th graders before moving on to copper etched circuit boards. There aren't enough copper plates for all three students to make their boards, so this activity gave every student the opportunity to play with the concepts a bit. The tape is sticky, (duh) so you have to be careful when making your corners since the adhesive won't conduct. Nevertheless, we've found it to be relatively easy to work with. Students engaged well with the lesson.

First of all, this tape is super thin, which makes it much harder to get smoothed properly onto your glass (it tears constantly). If you do persevere, the glue that bonds the tape to the glass melts and comes unbonded as soon as you get it hot with a soldering iron. I had to completely restart the assembly of my first project with it because glass pieces kept falling out of their little copper tape sheaths. Save yourself the headache and get better copper tape!
