Some gift ideas are inherently goofy, and this is a member of that species. The Plasma Mug induces an orange plasma between the walls of an evacuated, double-walled glass mug. This creates an eerie orange glow (best appreciated in low light) at the bottom of the mug while it's sitting on its electric coaster. When you touch the mug to pick it up, you'll also see fiery traces if a finger touches the outside wall of the mug. The mug has an amazing display of orange plasma lightning inside the glass. Place mug on the electronic coaster and orange plasma lightning radiates inside the mug. Simply touch the mug to gather the orange plasma lightning to your fingertips. When the mug is removed from the electronic coaster, the orange plasma lightning stops. The mug is clear hand blown glass. The electronic coaster is black and has a on/off switch. The plasma mug is suitable for use with any hot or cold beverage. Being wireless and battery powered this plasma mug with electronic coaster is completely portable. Ideal for parties, home bar or just for fun. The electronic coaster uses 8 x "AA" batteries (not included) or an AC adaptor (not included). The plasma mug is 5.5" high and has a 3" diameter and the electronic coaster is 5" wide.
