WATER BLEEPER

You will need two pieces of aluminium foil and some sticky tape.

Step 1

Make two square sheets of 
aluminium foil about 10cm x 10cm.
Stick the Jack Plug wires to the top
of each aluminium foil sheet.

Step 2

Join the blocks together 
as shown.    

Connect the BATTERY BOX 
and plug in the Jack Plug.

Step 3

Place the Logiblocs on the edge of a basin but be careful 
not to get them wet !  Fill up the basin to half full.

Hold the two aluminium foil sheets one
in each hand but do not let them touch
and slowly lower them in to the water.
The BLEEP should go off since the 
water acts to complete the circuit.

Now experiment with the water sensor to find other ways 
to let water trigger the Logiblocs.  Fix the sheets to the side 
of the bath to warn you when it has reached the right level !
