Electrodes, Mini Light Bulbs

Electrodes for fruit/potato batteries, conductivity, thermal experiments; extra large surface area. Great price when you buy just one; unbeatable prices on quantity.

Strips are 3/4" x 5" (19mm wide x 130mm long): more surface area means better results.

Note: Strips are alloys, not pure metals and are intended for middle to HS level experiments.
