Glow in the dark 260 spirals Why not?!?!! Everyone always asks why am I adding HI-FLOAT. Modeling balloons especially 260 balloons are a thinner balloon. This allows the air to escape faster than a regular balloon. Using HI-FLOAT to coat the inside of the balloon prevents the air from escaping as fast. The smallest bottle of Hi-FLOAT fits in a 260 and they also sell a 260 adapter kit that is especially made for this! * Neon 260 balloons from sempertex betallic . . . . #neonparty #neonballoons #glowinthedarkparty #glowinthedarkballoons #hifloat
