Step 2
Put the blocs together as shown and plug in
the Jack Plug into the IN block.
Step 3
Now keeping the pads separate, place one
or two fingers on one pad. Get someone to
ask you some questions about you or your
friends. Each time you give either a true or
false answer put one or two fingers from your
other hand onto the second pad. The sound
level of the BLEEP will change depending on
how hard you press or how much your hands are
sweating (because of telling lies!).

LIE DETECTOR
We can use the Logiblocs to make a Lie Detector. This uses
the effect that when people do not tell
the truth they usually sweat which
increases the electrical conductivity of
their hands.
Step 1
Make two hand sized aluminium
foil pads and lay them side by side
on a table, making sure that they
do not touch. Fix with tape the
metal ends of the Jack Plug wires with
some sticky tape, one to each piece of foil.

You can also do this with two
people. Put your right hand on the
right pad while your friend puts his
or her left hand on the left pad. Ask
each other questions and then join
your free hands together. You will
find that the Logiblocs can be
triggered through you both! This is
because your bodies also can
conduct electricity.
