Yes, but the water will spill out.
It depends how great and where the spill is. There is hardly likely to be a huge environmental spill or problem in Virginia Water. If you believe there is a problem the 'phone the emergency services.

It would depend on the extent of the oil spill. If it is a major spill in the ocean then it would cost a bomb.
Freeze it first. Alternatively, fill it with oil so that when you knock it over it won't be water that you spill.
surface tension
the current of the water
This is a fact, not an insult.
Liquid things are something the like water. Because water is something that can spill and make a mess. Also solid cant spill but it can drop.
No it should not as the oil spill is in salt water. Unless a city on the coast near the spill draws their drinking water from the ocean and desalinates it it shouldent effect the population on the gulf coast
