Bottle Cap Magnet
A great upcycling project, bottle cap magnet.
Bottle cap magnet

With the help of disc magnet Ø 25.0 x 5.0 mm Y35 ferrite - holds 900 g (they fit pretty well) I had the following idea: Drink bottle caps that my wife and I liked were carefully removed and collected.
The cork is cleaned and dried. Next, apply a little magnetic super adhesive in bottle with dispensing needle - 20 gr. - to the back of the cork and the ferrite magnet - press firmly together and wait a while - done.
