Yes, that small, orange, plastic box with the pokey prongs is your new Liquid Level Indicator. Here's how it works.
First, slide two AAA batteries into the bottom of the indicator. Now, grab a glass, and hang the device on the rim, with both prongs reaching down into the cup. Just like you'd hook your finger over the cup, only it's a bit more ... well ... civilized.
Now, try pouring your first drink. You'll notice if you're pouring something really hot that the steam will cause the indicator to chirp a bit. Never mind that. You're listening for the steady tone that tells you the probes have detected liquid. ... There, the liquid is now within an inch of the top. Stop pouring, pull off the indicator, and enjoy. But wait ... don't forget to pour a few glasses of juice for your friends first. They'd really appreciate it on a hot day in summer. But they'll think your new gismo is pretty cool, too. Then wipe it off with a damp cloth, and toss it into the cupboard next to the cups.
Remember, it's small for a reason. If you're pouring coffee to help out at a local fund-raiser, take your new indicator with you. It'll save you a lot of burnt fingers, and be more sanitary as well.
