Verify simple and easy demonstration teaching aid of air buoyancy existence

The utility model discloses a verify simple and easy demonstration teaching aid of air buoyancy existence, including balloon, bottled carbonated beverage, put the mint in the balloon, the balloon overlaps at the bottled carbonated beverage's who has opened bottleneck and ties up and seal, still include a gravity measurement device, cooperate with balloon, bottled carbonated beverage. The gravity measurement device be the electronic scale, balloon, bottled carbonated beverage place on the electronic scale. During the use, at first measure balloon, bottled carbonated beverage's weight, a beverage in the mint in the balloon and bottle, then in pouring the mint in the balloon into beverage, the mint can make gaseous a large amount of effusion the in the beverage, leads to the balloon inflation, electronic scale or force transducer can be accurate the change that shows its weight to verify the existence of air buoyancy. Whole process is rapid, the phenomenon is obvious, all has important effect to efficiency that
