Ultra Hi-float 150ml + pompje (ca 50 ballonnen)

The float time of helium-filled balloons is approx. 12 to 18 hours. However, if you would like a longer float time, it is necessary to treat your balloons beforehand with Ultra Hi-float. This is a type of gel that seals the pores of the balloon and thus keeps the helium inside the balloon for approx. 1 week. The procedure is as follows: using the pump on the bottle, put a tiny amount of Hi-float into the balloon. Spread the Hi-float evenly along the inside of the balloon with a rubbing motion. Then inflate the balloon with helium, tie it shut without tightening it too much, and keep the balloon at room temperature for at least an hour so that the Hi-float has a chance to dry. Only once the Hi-float is dry will it keep the helium inside the balloon. The result is a balloon that floats for at least 3 to 7 days. This amount allows you to fill approx. 50 balloons.
