I have a boy, he has a toy which need 3 batteries, but I only have 2 batteries. With an easy hack I can switch on the toy to work properly. What did I do?

    $\begingroup$ This is a perfectly appropriate real puzzle, quite in line with many others tagged the same. The tag's meaning has evolved (see, for instance, Meta post Real tag adjustment) and its short description could still be improved significantly. Puzzles from the wild, like this one, make valuable contributions to this site, especially toward authenticity in the pursuit of understanding all kinds of puzzles. This puzzle's being put on hold dismays me. $\endgroup$ – humn Oct 13 '17 at 11:59

    $\begingroup$ @humn, well, this puzzle deserves a place, but in lifehacks.stackexchange.com I feel. $\endgroup$ – Mea Culpa Nay Oct 13 '17 at 12:06

    $\begingroup$ @MeaCulpaNay Considering how the accepted answer is unlikely to work properly, this looks to be a barebones lateral thinking puzzle rather than a practical "life hack". $\endgroup$ – MikeQ Oct 13 '17 at 12:58

    $\begingroup$ Also, @MeaCulpaNay, this is a site for puzzles in general, not just for puzzles that have no place anywhere else. How is this puzzle not puzzling? $\endgroup$ – humn Oct 14 '17 at 0:02

Did you:

Directly connect one of the terminals to the opposite terminal with a strip of metal?

Problem:

This could potentially not give the toy enough power, stopping it from working.

Based on the tag for this question,

Use a small, reasonably shaped potato / similar root vegetable(s) and join them with external wires to have the required power of 3 batteries.
