3. Sharpen your scissors
If you need to sharpen your scissors and get rid of rust, cut a piece of foil 7-10 times, just as described in this blog.
4. Extend battery life
If your batteries have run down and you do not have any new ones, use some aluminum foil. Place the foil according to this instruction.
5. Remove static electricity from your clothes
Put some foil balls in the washer together with the laundry (look here for details). After washing, your clothes won’t accumulate electricity and attract dust and hair.
