After watching a professional entertainer we bought for Christmas a balloon modelling kit. The entertainer easily blew up the long balloons but when we tried not one of us could manage without running the risk of bursting a blood vessel. I appreciate that a pump would be the easiest method but as I have seen them blown up manually I would like to know what the trick / technique is to impress the kids and adults alike.
really stretch all the balloons first of all and also pre-blow them up and then let the air out. then when you come to actually do the stuff properly the balloons will inflate quickly and "professionally".
We had a great laugh at our Christmas party with those long balloons that fly all over making a farting noise when you let them go. However, they were almost impossible to blow up before we realised that you placed a small tube into them before inflating.
