5 Foil balloons Sonic 18"/46 cm

Fun Sonic balloon ideal for a birthday or as a gift for a Sonic fan.

Note: The balloon is to be filled with helium, when filled the balloon floats for approx. 3-7 days. The balloon can be refilled using the self-sealing valve.

Use a balloon weight to prevent the balloon from flying away unintentionally.

Expert tip: If the balloon starts to lose helium, an adult can refill it with a little air via the valve using a straw. This will allow it to float for many weeks until it eventually runs out of helium.

Caution!  Never inhale or deliberately inhale helium as there is a risk of suffocation. Do not allow the balloon to fly, as it is electrically conductive and could cause damage to high-voltage power lines.
