[Bloominglabs-announce] Parts for the Wonderlab squishy circuits kits

[Vic Kelson]

I can't recall if we were able to get enough current to light an LED, but we checked the voltage with a meter. Hans will recall if the squishy battery could light a LED.

By hooking them up in series, we boosted the voltage until the internal resistance made it unworkable. But we did hook up 2 or 3 cells.
