超微距下的酵素泡泡相連
(Enzyme Bubbles Under Super Macro Lens)

鳳梨酵素經過激烈搖晃後，產生非球型（近扁平狀）且形狀多變的泡沫、泡泡之間相隔管狀的氣管，作為輸送空氣之用。透過超微距鏡頭觀察，可見微小的空氣泡泡，在很小很精緻的透明管中（約0.02毫米）移動，大泡沫經由透明氣管抽光小泡沫的空氣，直到小泡沫縮小消失為止。

When a bromelain mixture is violently shaken, non-spherical (nearly flat) bubbles of varying shapes are produced. The tube-like structures between the bubbles are used to transport air. Using a super macro lens, it is possible to see tiny air bubbles moving inside the very small, fine and transparent tubes (approximately 0.2mm). The larger bubbles draw air from the smaller bubbles in the tubes until all the smaller bubbles have shrunk and disappeared.
