A goldfish in a wheelchair conquers the internet – PlayGround+

Her friend Derek, 20, works at an aquarium shop in the same city. A customer recently came to Derek with a goldfish that was suffering from swim bladder disease – a disorder that prevents fishes from controlling their buoyancy in the water. When the bladder is infected or deformed it can cause a fish to float to the top of the water, swim upside-down, or lean heavily to one side. As this particular fish’s problem was incurable – meaning it was condemned to spend its life stuck at the bottom of its tank – Derek had an idea for a way to help the little invalid out: he made a tiny goldfish wheelchair. The story already has more than 25,000 retweets, 75,000 likes and and a whole load of comments – mainly expressing delight at this touching display of kindness towards our fishy friends.

Facebook pays 10-year-old Finnish genius $10,000 for exposing flaw in Instagram

Ten-year-old Jani, whose last name isn’t being shared at the request of his parents, uncovered a way to delete any given comment on Instagram, the photo-sharing company that Facebook bought for $1 billion in 2012 — and which Jani, so to speak, pwned.

The consumer group claims supermarkets are pushing illusory savings and fooling shoppers into choosing products they might not have bought if they knew the full facts. Examples raised by Which? Include Tesco flagging the “special value” of a sweetcorn sixpack when a smaller pack was proportionately cheaper, and Asda raising the individual price of a product when it was part of a multi-buy offering in order to make the deal more attractive.
