We supplied 80 x 36″ Lime Balloons helium filled to The Royal Academy, Piccadilly. Arriving at 6am 3 crew had all 80 filled & ready for 8.30am.
They lasted well for 24 hours but then the extreme heat kicked in. The hot weather cooked the moisture from the latex and made the balloons brittle. They reduced in size in the cool overnight temerature and then shattered when things heated up the following day.
