Kurt Steiner holds the world record for stone skipping, with 88 skips achieved on a lake in Pennsylvania's Allegheny National Forest. From Wikipedia:
An early explanation of the physics of stone-skipping was provided by Lazzaro Spallanzani in the 18th century.
The stone generates lift in the same manner as a flying disc, by pushing water down as it moves across the water at an angle. Surface tension has very little to do with it. The stone's rotation acts to stabilize it against the torque of lift being applied to the back.
Research undertaken by a team led by French physicist Lydéric Bocquet discovered that an angle of about 20° between the stone and the water's surface is optimal. Bocquet and his colleagues were surprised to discover that changes in speed and rotation did not change this fact. Work by Hewitt, Balmforth and McElwaine has shown that if the horizontal speed can be maintained skipping can continue indefinitely.
A team from Italy recently broke the Guinness World Record for the “most robots dancing simultaneously.” At an event in Rome, 1,372 Alpha 1S robots danced and dabbed in unison earning Team TIM S.p.A. the title. Video: Watch more than 1,300 robots dance simultaneously to break a world record
This is Keon the Irish wolfhound from Westerlo, Belgium who broke the Guinness World Record for the longest on a dog. Keon’s tail is 76.8 cm (30.2″) long, beating the previous record-holder also a wolfhound, by 4.5 cm (1.7″). (Guinness World Records)

Remember when the default state of your online presence was anonymity? That’s not so clear-cut anymore, and the worst part is you may not even know who is using your data or what they’re using it for. Small wonder that so many people are choosing to surf through virtual private networks. VPNs filter web access […]
