19 November is an important day in the world's calendar.

Sure, it's the 25th anniversary of when Reagan and Gorbachev first met face to face during the cold war, and it's also 41 years to the day that Apollo 12 astronauts Pete Conrad and Alan Bean became the third and fourth humans to walk on the Moon.

But forget all that for 19 November's most crucial aspect is that it's National Toilet Day. No sh*t.

And to celebrate why not make use of the Flush Tracker from Domestos, which lets you keep a record of where your flush contents are, and the speed your droppings travel?

You enter your postcode and the time you flushed, and the site shows an animation of it travelling through the sewer system. Our average flush speed is about 4.54mph. You can also take a look at how other flushes around the world are doing.

It adds a whole new literal meaning to "looking up sh*t on the Internet", at least.
