2. Computers: put some isopropyl alcohol in one and seal it shut. Use another and put Q-tips in it (Leave off top if it’s a small bottle). Use these to clean your mouse ball, mousepad, and keyboard. You can cut down on germs by storing cosmetic squares or circles in a med. to large one, and lightly wet one down with the alcohol to clean off keyboards and cut down dirt & germ passing on shared computers.

3 Small Boats: Use one to store a spare key:
-Tie a string tightly around it’s top and wind about 8-12 feet around the bottle then store under a seat. If the boat turns over, it will be easily retrievable, and will float to the surface when dislodged (if capsizing didn’t do it)
-Keep a copy of your driver’s or fishing license in there, anything small you can’t risk losing. For visibility’s sake, before tieing it to the boat you can wrap with some bright orange or reflective tape, you can even use a child’s leftover colorful stickers then wrap with scotch tape for water tightness.
