1 Minute Timer (60 Seconds) - Online Timer.

One bottle is upside down, on top of the other. Fill the top bottle with water, through the hole on the side. Time how long it takes for the water to flow through the caps to the bottom bottle. Adjust the amount of water in the bottle until it takes exactly one minute for the water to flow through [source: Schultz].

The floating timer allows control of routine activities for a clock. Any of your clocks can be accessed through the floating timer. Tip: If you need frequent access to your clocks, you can add the floating timer shortcut to your Quick Access Toolbar.
