Lie detector
YOU WILL NEED
+ your humidity detector
+ and additional household
items: adhesive bandage,
test subject :)
HERE'S HOW
1. Find a test subject and use the
bandage to tape the two loose wire
ends to the palm of his or her hand.
Carefully position the wires so their
ends are close to each other but do
not touch. Before you start the lie
test, the detector's red LED should
be lit.
2. Start by asking your test
subject some harmless
questions, and then
proceed to trickier and
more awkward ones.
