    DIY LED Pressure-Sensitive Coasters

    This is an extremely simple, but cool idea for a coaster. It works by placing small watch batteries inside an acrylic coaster. Then connect one end of the LEDs to the battery while bending the other LED into an L-shape. Once a full, frosty beverage is placed on the coaster, the other LED contact will touch the battery and light up. Follow the linkage for the detailed instructions, including pictures.
