This hand-cranked generator creates static electricity. Set it on a lab table and simply crank to demonstrate static electricity. Try the electric whirl - watch the vanes spin around ever faster as more electricity is produced. Or the electric plume - colored streamers fly apart as each strand acquires the same electrical charge. The discharge wand draws out a spark over thin air. Easy to carry and store. 28" H. 10" diameter. Includes 16" L discharge wand with transparent plastic handle, electric whirl, electric plumes, adaptor for attaching accessories, and instructions. Grades K-12.
