The Tilt 'n Tap

I was drinking lemonade this afternoon, and Cory decided he wanted a drink. So, he picked the glass up; the coaster stuck to the bottom of the glass and then fell off, getting water all over the coffee table and the papers on the table. I guess he hasn't mastered the tilt 'n tap yet. When you pick up a sweating glass, you tilt it slightly. When the coaster starts to come with the glass, you tap the edge of the coaster on the table to knock it off. That way the coaster stays on the table, instead of sticking to the glass and then falling off at the worst time.
