Step 1: Materials:

to get revenge now, all you need are:

-a bic pen, or a very similar style of pen with a cap
-coffee(and a coffee machine, you silly goose!)
-scissors for cracking open the pen
-a gluegun to make it watertight

(a funnel and tape turned out to be very handy for filling the pen with coffee)

and last but not least, a victim!!! >:P

Step 4: Adding the Coffee:

for this, i used a small funnel taped to the open end of the pen. this really helped keep things clean. just in case, do this step above a sink.  just pour the coffee in until it is full.

do you really need a glue gun

yes, you need a glue gun, if you do not make it watertight the coffee will leak out before it is supposed to, ruining the effect.
