Steve Mould demonstrates the very odd physics of the bead chain used in vertical blinds. He explainz:

The reason it self siphons is that the chain pulling down outside the beaker is longer (and heavier) than the chain pulling down on the inside of the beaker.The reason the chain loops up higher than the rim of the beaker is a bit of a mystery. I think it’s to do with the fact that the beads are changing direction and it can’t do that instantaneously as that would represent infinite acceleration. So a big loop is formed. I don’t know, something like that.


the-100-mph-bicycle-7597A new design from Donhou Bicycles in the UK that features a huge 104-tooth chainring, with a diameter of nearly 17 inches (43cm)  (most road bikes have about 50 teeth in their largest ring).

Theoretically, the hand-made, ultra-low handlebarred bike – which premiered at the UK Handmade Bicycle Show in Bristol earlier this month – can reach speeds of 100mph, though it’s only been clocked to 67mph so far.


Korean artist Yeong-Deok Seo uses tightly-knit configurations of welded bicycle chains and industrial steel links to create his intricate sculptures.

While impressive in their intricacy and the apparent skill required to create them, the artwork’s titles such as Infection – Anguish, Infection – Ego, and Addict, suggest the rippled surface created by the materials is not an arbitrary decision.
