most people know that metal coins won’t float in water but for this experiment
float in water but for this experiment
float in water but for this experiment I’m going to show you a cool little

one-yen coins one-yen coins are kind of
one-yen coins one-yen coins are kind of like Japanese pennies and there’s a good

Japanese exchange students these common coins around two-and-a-half times
coins around two-and-a-half times
coins around two-and-a-half times lighter than our pennies because they’re
lighter than our pennies because they’re
lighter than our pennies because they’re minted from aluminum instead of zinc but
minted from aluminum instead of zinc but
minted from aluminum instead of zinc but that doesn’t mean they can float in fact
that doesn’t mean they can float in fact
that doesn’t mean they can float in fact if you try to sing a few into a bowl of

what’s really amazing is you can float
what’s really amazing is you can float as many coins as you want at the same
as many coins as you want at the same
as many coins as you want at the same time as long as they’ll fit in the bowl

but how does this work the answer is
but how does this work the answer is surface tension the attraction between

surface tension the attraction between the water molecules at the surface is
the water molecules at the surface is
the water molecules at the surface is just strong enough to support the weight
just strong enough to support the weight
just strong enough to support the weight of an aluminum coin without letting it
