A battery operated door bell,
a stiff wire coat hanger, a piece of wood and some insulation tape.
find a battery operated buzzer or door bell (These items can often
be found in cheap household stores). Do NOT use a mains voltage operated
device as you will stand the risk of death through electrocution.
A door bell is perfect, as all the wiring is already done and the
voltages are normally low and safe. Ensure you choose a device that
uses less than 24 Volts. The coat hanger loop and twisted trail simply
make a switch that replace the push button switch of the door bell.
You should have two wires when you remove the door button. When you
touch them together the buzzer should sound! This is a good test before
you start. THE TWISTED LOOPED TRAIL: Take
a block of wood and drill two deep holes that are the exact diameter
of your coat hanger.
Bend your coat hanger into an interesting shape with loops and twists.
Insert each end into the hole so that it is firmly held held in place.
Twist one of the switch wires around one side of the trail. Place
plenty of insulating tape on it. This doubles up as a resting place
for the loop so ensure that no bare metal is visible other wise your
buzzer will keep sounding when not in use! Add the tape to the other
side to make another 'Safe' area for the loop to rest. THE LOOPY LOOPED HANDLE: Using the stiff
metal from a coat hanger, form a loop on one side. Attach the other
switch wire to the other end by tightly twisting it around and holding
in place with insulating tape. Form a handle. At this point it is
worth noting that the larger the hoop and shorter the handle length
the easier the game will be! Place the hoop over the twisted trail
and close up the gap so it cannot be removed. If the metal of the
hoop touches the non insulated metal of the trail the buzzer should
The object of the game is to carefully
move the handled hoop over the twisted hanger from one end to the
other without the buzzer sounding. It takes great skill and a steady
hand! Use the green 'Jello' buttons to pause
and play the animation!
