This belief seemed to spread in April 2011 via twitter. Due to Ryanair's reputation as being overly greedy at the cost of the consumer, I think many people have simply assumed that this claim was true. It does not appear that it has been looked into too conclusively, but the investigations that have been done indicate that the claim is not true. Popular ...

The excellent Skeptoid blog has an entry for this very question. It's an entertaining read and well sums up the typical reasoning behind the myth and debunks them. From his conclusion paragraph: However, there's at least one remaining possibility that can explain what's being reported, and it doesn't require any new discoveries about anatomy or fans, or ...

No... There is no evidence that copper bracelets are any more useful than a hologram, or an ion bracelet, or a piece of amber, etc. (See below for a minor caveat.) Any effect that could be out there is nothing more than the [placebo effect] (Link to abstract on placebo effect for this specific mechanism)1. If you had read the linked question, you should ...

The label is real. It is a joke on behalf of the manufacturer, the Norwegian company "Ugly Children's Clothing" (They now seem to be trading as Marius Kids; the history/relationship was too convoluted for Google Translate to adequately explain.) Evidence that it hasn't been faked in Photoshop comes from the various different sources of different clothes ...

Can anyone confirm if this actually takes place with RyanAir or with any other airlines?

The question boils down to: Given we have an electronic device that can be triggered remotely (to lock or unlock a door), is it possible to produce a hardware-based solution that can trigger it by: touching bananas connected to hardware? pushing buttons on a wireless device in the shape of a wand? detecting when you raise your eyebrows, using a device that ...

The word "scam" suggests fraudulence - a deliberate intention to deceive. It is a strong accusation, and we should be careful about wielding it without evidence. Given Leap Motion claim that they will not charge until the product is shipped and that they bill via credit-card, which enables consumers and the banks to recover their money if they charge ...

Back in 2012 this probably wasn't answerable, now after Gazelle's research which was conducted in 2014 I can attempt to answer this. The good news: it prevents it from dying. The bad news: it isn't the most effective (more like least effective). Gazelle, an eCommerce company, which lets people sell their used cell phones and pays consumers for used or ...

They probably do. While I couldn't find evidence for Louis Vuitton destroying their unsold products, except for the original article, there are proof for other companies doing it.

Your co-worker is right, normal paper deteriorates due to its acidity and due to oxidation. Paper in Europe was originally made from cellulose sourced from linen and cotton rags. This made strong paper structures, owing to the long cellulose chains. The degree of polymerisation - a measure of the average number of glucose molecules in a polymer ...

Looking at their own website, the product they describe has no electrical or mechanical parts at all. "Made from only 2 pieces of paramagnetic titanium".
