most people know that metal coins won’t float in water but for this experiment

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

what’s really amazing is you can float as many coins as you want at the same

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
