Drea experiments with a technique suggested by a colleague from California, of double-stuffing a larger balloon inside a smaller one, to see if the outer one will pop first while leaving the inner one intact. After perfecting the seal of the balloons on the inflation tube, which allows us to measure inflation pressure, Drea sets off on her quest. The combined thickness of the two balloons created considerable back pressure, which posed quite a challenge to her breath control, since she did not have benefit of a one-way valve, and could not squeeze the balloons shut between breaths.

Drea experiments with a technique suggested by a colleague from California, of double-stuffing a larger balloon inside a smaller one, to see if the outer one will pop first while leaving the inner one intact. After perfecting the seal of the balloons on the inflation tube, which allows us to measure inflation pressure, Drea sets off on her quest. The combined thickness of the two balloons created considerable back pressure, which posed quite a challenge to her breath control, since she did not have benefit of a one-way valve, and could not squeeze the balloons shut between breaths. Both her abs and her face muscles received a good workout, and by the end, her cheeks had expanded to their limit! This experiment has definitely captured out interest, and will be re-run using other balloon combinations.
