Cleaning glass sphere
Tenacious algae inside glass require tough measures

Recently, I tried to get rid of the algae inside the glass spheres that help water the flowers.
Inspired by the application Cleaning bottle and hydration pack, I wanted to use magnets to get inside the spheres. Unfortunately, algae not only stick to glass like crazy, they are also very slippery. Due to the small opening I used a small magnet wrapped in a cloth, which was not effective in cleaning the algae.
Then I had the idea of making a mini stainless steel sponge that can scrub off the algae.
To keep the wire ball in place and protect the magnet from corrosion, I dipped it into the adhesive.
Note from the supermagnete team: Most likely, the ring magnet will start to rust and lose its magnetisation eventually, despite the adhesive. Therefore, you'll need to replace the ring magnet from time to time.
Steel wool itself is a little magnetic. Maybe this application also works with only steel wool on the inside and a magnet on the outside. But a small magnet on the inside definitely enhances the surface pressure.
