Giant balloon inflation
For inflation, we recommend that you have a tape measure and get 2 chairs, measuring a space of 80cms between the 2 chairs. When attaching to a full tassel tail, inflate the balloon fully with helium in between the 2 chairs until it is touching each chair and then you will know it is filled to exactly the right size. On a hot day, under-blow the giant to 70cms to preventing popping.
For giant balloons on plain ribbon or short tassel tails we recommend a ratio of 60:40 helium to air. Just follow the instructions above, inflating the giant first with approx 15cms of air, then continue with helium.
