I think i broke my laptop... dell inspiron mini?

i got this laptop for christmas last year. yesterday i was tying a water balloon for my brother and it spilled all over my computer. i covered it with rice (thats what you do for cellphones, right?) and let it dry out for 24 hours. i tried turning it on and it didnt work. is there any way i can fix this? and is there a warrenty for this on my laptop? dell inspiron mini. plus, how do i tell my parents? they already think im irresponsible....
