How many 2 liter bottles can be filled in 2 minutes?

Depends: what's your water source? How fast is it flowing? How large of an opening do the bottles have? How many can you fill simultaneously? If we're talking a hundred bottles simultaneously at Niagara falls, I'd say all 100 could be filled in 2 minutes; if we're talking standard soda bottles at a tap in the kitchen, depends on how fast you move & how strong you turn on your sink.
