Very interesting but the sound of a dripping tap can drive me crazy.

Taborek uses high-speed video to capture the motion of drops and bubbles coming apart. Knowing the details of this “pinch-off” process is important when designing inkjet printers, because ink must form a single droplet without trailing liquid. It also is useful in biotechnology when fluid is used on microchips, and it has applications in cosmetics, food and structural materials industries.</P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.sciencedaily.com/releases/2009/02/090201124930.htm"><P>The scientists discovered the main difference between drops and bubbles is the density of the liquid inside. The pinch-off process is bubble-like until a certain density is reached, then the pinching becomes drop-like.</P></blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/EBDA7591-3207-4485-8DA4-71811052CCDB/blog/" title="blog or email this clip"><img src="http://content6.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
