plasma globes
Touching makes lightning
Plasma globes are decorative glass spheres containing low-pressure gas through which electrical discharges create colorful, lightning-like tendrils radiating from a central electrode.
Touching the glass draws the filaments toward your hand.
Popular as novelty items and science demonstrations since the 1980s: Every kid wanted a plasma globe after seeing one at the mall.
