A quick, cheap, and simple way to turn your extra bottle caps into simple yet cool fridge magnets. Plus graphic designer in my loves the variety, color, and visual dynamic that a few bottle caps on a fridge can create.
Step 1: Materials
Here's the bare bones materials list:
- bottle caps
- sandpaper (I used 220 grit... the grit isn't critical)
- hot glue gun
- hot glue sticks
- button magnets (1/2")
- 1/4" hex nuts
Notes on the magnets:
sure, one could use heavy-duty neodymium magnets, but they cost significantly more and for my purposes, the simple ProMag Magnetic Buttons (available at local craft stores i.e. Michael's, Hobby Lobby, etc. ) work well and come out to only a few cents per magnet. They sufficiently hold photos, postcards, papers, etc. And are soft enough that no damage could possibly be inflicted on fridge surfaces.
Notes on the glue:
You could easily go all out and use some heavy duty epoxy or other adhesive, but hot glue is simple, quick, and cheap. For these bare-bones magnets, hot glue does the trick.
using a nut helps space the bottle cap off of the fridge surface so there's no chance of scratching the surface, and creates a uniform distance between the magnet and the bottle cap. Using a large gob of hot glue usually creates a relatively uneven wonky mess.
One other note: I've found that the best way to remove bottle caps without causing any damage is to use the bottle-opener end of a wing-style corkscrew. The larger dimensions usually spread the force evenly across the cap so it doesn't crease or bend.
