To break the silence...

Ok, here's another one (And NO cheating! )

I am weightless, but you can see me. Put me in a bucket, and I'll make it lighter. What am I?

[BlueCat]

Light

[Traveler]

Thats pretty clever. And a correct answer I suppose, but I was looking for something else. (lighter, as referring to weight)

[BlueCat]

Helium :lol:

[Eriken]

If you put helium in a bucket it will just disappear upwards? If you turn the bucket, do you then but the helium in a bucket or on the ground?

The silly answer: Nothing

I can see nothing.. I can put nothing in a bucket, and if I take out something of the bucket it will be lighter then

The insulting answer will be left out, it would have been a comment about someone's brain

A balloon? (I had to have a spell checker to spell that ops: )

[BlueCat]

I was talking about pink helium which is an entirely different thing. And don't worry about your brain Eriken, we don't mind.

Ok is it an anti gravity magnet?

[Paulius]

this riddle is flawed, everything is composed of particles and all particles have mass. Now if we elliminate the weight criteria I would go with acid.

[Traveler]

Nope, helium is not correct as I cannot see that. And its not a balloon either because a balloon does have some weight.

When you put [answer] in the bucket it will become noticably less heavy.

{edit} you're getting close Paulius

Fire!
