Deluxe Hero's Fountain
Graphic fluid pressure demonstration
For a large, dramatic presentation your whole class will love, just set up Hero's Fountain, put it on a counter, and pour water in its top--the fountain actually spouts into the open air! Water in the fountain's top reservoir enters the lower bulb, which contains air. Air is forced up to the top bulb, compressing the air in that bulb, and forcing the water to spout out of the upper tube. Entire unit is 50cm high.
Hero噴泉
這是一個簡易,很受歡迎的實驗。只要將儀器裝置好,在上端倒入水即
可,噴泉最後即會噴出。上端含有空氣的水會流至底下,下面的空氣即
被迫往上並壓迫上面的空氣, 因此水便會由上端噴出。整個裝置為50
公分高。
