Sometimes the best Instructables are the simplest ones. I saw this tip on Popular Mechanics list of their top tips and decided to turn it into an instructable. This is a really simple project to make and will save you some money buying watering cans, plus if you have already built a rain barrel from one of the excellent rain barrel Instructables, you will already have a good way to easily fill your homemade watering can.
Tools needed for this Instructable:
1 empty laundry detergent bottle.
1 drill and drill bit.
Step 1: Rinse the Bottle
Rinse out your empty laundry detergent bottle thoroughly.
