A very famous balloon shape is hearts. We can find in this collection latex balloon hearts 12" & 6". The latex balloon hearts can be inflated by helium or by air. To inflate the balloons with air we use a simple balloon pump ,or an electric one, even simply by the mouth and we decorate them on a balloon stick or as we want. If you inflate with helium the 12" heart latex balloons ,will hover around 16-18 hours. They need 0.009 m3 of helium to fly. If we want our balloons to fly for much longer ,we should use HI Float. The lifting capacity of them is 7 gr. If we inflate with helium the 6" heart latex balloons ,will hover around 4 hours. They need 0.003 m3 of helium to fly.
