You can see it with the naked eye....if you put this in a barrel it makes it lighter...if you take this out...it makes it heavier....what is it?
Does anyone know the answer please?
Thanks a bunch.
If you put a hole in a barrel it will be lighter, if you put a bung in the hole it will be heavier.
yeah i would say hole too
A helium* filled balloon.
*or any lighter-than-air gas
