Science doesn't get any cooler than this! Tesla's Plasma Ball is a lamp and science experiment in one.

This lamp is a colourful way of observing electrical discharges and does double-duty as awesome decor. Named for Nikola Tesla, whose explorations into the world of electricity were so ahead of his time, people thought his experiments were real magic.

The globe itself is filled with three inert gases (neon, argon and xenon), and a high frequency electrode is in the centre. Place your fingertips on the lamp and watch the filaments glow. It's like creating your own personal bolt of lightning from the electrode to your finger!
