Wiggle the nail to remove it from the bottle.

Refill the container as necessary.

If the cap is too hard to pierce, heat the nail over a flame first. Hold the nail with a pair of pliers so that you don’t scorch your fingers. [2] X Research source If your bottle had a thick lid (ie: detergent bottle), use a drill and a ⅛-inch (0. 32-centimeter) drill bit instead.

If you used a drill bit, you will need to rinse the bottle out first to get rid of any plastic dust.

If your bucket is deeper than your bottle, dip the bottle only ¾ of the way. The bottle will only fill to the same water-level that’s already in the bucket.
