The pool under a ten metre diving platform, built exactly deep enough to stop you.

-10 m

Every ten metres of water adds another atmosphere of pressure. Your ears knew first.

A trampoline, fully buried, still bouncy, deeply unwise.

The bottom

You have run out of shaft. That took some doing.

How to play Bottomless

Scroll down, then keep scrolling. The shaft runs from the surface to a punchline, and every so often a marker tells you what sits at that depth. On a phone, swipe or drag the shaft upward. On a computer, use the wheel or the trackpad, hold the down arrow to keep falling, or press space for one big drop. Home pops you back to the surface. Your depth ticks up in the header while you sink and your deepest ever is saved between visits. Press surface whenever you want to stop and you get a card with how far down you got.

Tips

About Bottomless

People are bad at guessing how deep things go. A swimming pool feels deep. The recreational scuba limit is only 40 metres, and the deepest hole anyone has ever drilled stopped at 12,262 metres, which is not even halfway through the continental crust. Bottomless puts all of that on one long vertical scroll so the distances land properly instead of sitting in a table. The real depths were checked against published figures, including the 10,935 metre floor of the Challenger Deep and the snailfish filmed at 8,336 metres that holds the record for the deepest fish ever seen. Below the drilled rock the shaft carries on into things that are not real at all.
