Use one timer for controling multiple forms

this not for a class. I am playing with VB 2008 using .Net 2.0 as the target to compile to and am trying to figure out if it is possible to create multiple countdown timers one in each form using a single timer.
I have attemtped but the logic escapes me. If this is not possible I know how to use a timer on one form for that form.
thank you:eek2:

Form1
Method: DoSomething()

Form2
Method: DoSomething()

Form3
sub Timer_Elapsed()
Form1.DoSomething()
Form2.DoSomething()
Me.DoSomething()
end sub

?
