The pitch drop experiment is on public display on Level 2 of Parnell Building in the School of Mathematics and Physics at the St Lucia campus of the University of Queensland.Hundreds of thousands of Internet users check the live stream each year. On 24 April 2014, Professor White decided to replace the beaker holding the previous eight drops before the ninth drop fused to them.

Perch lets you turn your phone or laptop into a live home monitoring service.I use the time based schedule to only record Mon-Fri 8am - 6pm. The pitch drop experiment is a long-term experiment that measures the flow of a piece of pitch over many years.Pitch is the name for any of a number of highly viscous liquids that appear solid, most commonly bitumen.At room temperature, tar pitch flows at a very low rate, taking several years to form a single drop.Parnell poured a heated sample of pitch into a sealed funnel and allowed it to settle for three years.

In 1930, the seal at the neck of the funnel was cut, allowing the pitch to start flowing.The University of Queensland pitch drop experiment, featuring its then-current custodian, Professor John Mainstone (taken in 1990, two years after the seventh drop and 10 years before the eighth drop fell).of the experiment was started in 1927 by Professor Thomas Parnell of the University of Queensland in Brisbane, Australia, to demonstrate to students that some substances that appear solid are, in fact, very-high-viscosity fluids.The eighth drop fell on 28 November 2000, allowing experimenters to calculate that the pitch has a viscosity approximately 230 billion (2.3 and it is expected that there is enough pitch in the funnel to allow it to continue for at least another hundred years.This experiment is predated by two other still-active scientific devices, the Oxford Electric Bell (1840) and the Beverly Clock (1864), but each of these has experienced brief interruptions since 1937.I don't want to record on my indoor cameras when people are at home. I have 6 foscam cameras in and around my house so I would also need the ability to add ip cameras. When I login to Smart Things from your site, I am able to gain control of the light that I gave it access to, but I am not seeing Perch show up in my list of Smart Apps or anywhere else in the Smart Things app or IDE.
