No helium needed! E-Z Balloon Sticks and Balloon Cups seal and hold air-filled latex or foil balloons upright eliminating the need for hand-tying of knots. Use with 9 to 17 inch latex balloons or 18 to 20 inch foil balloons.

Okay...here is the proper way to do it... calculation is as follows; 0.2 to 0.5 x cm2. This means that for a T25cm2 flask the volume range is 5-12.5mls for optimal CO2 penetration. T75cm2 flask = 15-37.5mls. T150cm2 flask = 30-75mls. T185cm2 flask = 37-92.5mls. calculation is done by multiplying 25 (for a T25cm2 flask) x 0.2 = 5ml lowest volume. 25 x 0.5 = 12.5ml highest volume. 75 x 0.2 = 15ml lowest volume. 75 x 0.5 = 37.5ml highest volume and so on. The measurements are gotten by measuring the base of the flask (or bottom). T75cm2 flasks are about 8cm x 9cm. You can even stand the flask up and use it that way. For a T75cm2 flask the bottom measures about 7.5cm x 3cm = 22.5cm2 = 4.5 to 11.2 ml volume.
