Always be yourself,
Unless you can be a ________,
Then always be a fill-in-the-blank.

At last... a heat absorber that is not a heat sink too.

That is almost as slow as the pitch drop experiment which began in 1927.

In the 89 years the experiment has been running, nine drops have fallen so far. Nobody has yet observed a drop falling. Since the 1990s the experiment has been continuously monitored by a Web camera, but when the eighth drop fell in November 2000 the camera was offline and the event was not recorded. In April 2014 the ninth drop was broken off while replacing the beaker beneath the funnel, which had been filled sufficiently by previous drops to interfere with the experiment. There is a Web site devoted to watching for the tenth drop to fall.

One on camera?

Based on visual evidence that a drop has not fallen or a drop has fallen, the person performing the daily drop test check reports to the Pitch Drop Experiment Custodian the status of the drop. When he receives notice that a drop has fallen, the Pitch Drop Test Custodian rushes over to examine if indeed a drop has fallen. If it has, he then notes on the Pitch Drop Test Record the date, calculates the time interval since the last drop and counts how many drops have dropped.

I hope that the ambient temperature in the experiment location has remained constant!

I find it interesting and fun. Something to connect people of all ages.

OK. The drop does retain its shape for a time.
