Read receipt Nov 21, 2007
Microsoft Outlook has the option of requesting a read receipt for emails you send.  If your recipient reads the email you sent, a message gets sent back to you, assuming the recipient allows the read receipt to be sent. 

People at my job send out stupid emails.  And they send a lot of them.  And they send them to about 2000 people at once.  Every time I receive a mass emailed message that asks if I want to send a read receipt, I consider clicking no because the sender likely doesn't even know me, let alone care if I read the message or not.  Instead, I click yes, hoping the stupid sender is overwhelmed by 2000 read receipts all at once.  Have I mentioned I hate mass emails? #technology
Punching kids Nov 21, 2007
There's this thing that's found in normal everyday martial arts places.  It's called BOB, or Body Opponent Bag.

Instead of practicing your punching, kicking, elbowing, and kneeing on a bag (or a real person), you practice on a rubbery dummy that's about 6 feet tall.  It's good practice because most people, as it turns out, aren't cylindrical, so punching a bag isn't always very life-like. 

In martial arts places that also offer classes for kids, there's a similar thing called Bobby Bully.

It stands about 4 feet tall and has a mean face like a bully.  It teaches kids to punch other kids who look mean. 

An interesting thing happens at the kickboxing place I go to.  Our class is full of grown men and women, mostly in their early- to mid-twenties.  At the beginning of each class, we run around the mat in a circle to get our blood flowing.  Certain guys, as they run past the Bobby Bully, throw a punch or an elbow just for fun.  Since Bobby Bully is rubbery and relatively life-like, his neck bends at an impossible angle when he's punched hard enough.  Watching grown men punch a child-sized dummy is hard to explain.  If it's done with a serious face, these guys would look like sadistic criminals.  Done with a chuckle, it's harmless.  Either way, it helps us get ready to punch kids in real life.  And that's a skill everyone should have. #sports
Buoyancy Nov 21, 2007
This just in: 
Buoyant Force On Area Object Equal To Weight Of Water Displaced
An area object partially immersed in a liquid was buoyed upward Tuesday by a force equal to the weight of the liquid displaced by that object, witnesses at the scene reported. According to sources, opposing forces acted against gravity during the displacement. In addition, though the object reportedly seemed lighter, it only appeared weightless due to the fact that the density of the liquid surrounding it was only slightly greater than that of the object. As of press time, the object is still maintaining positive buoyancy.
Reminds me of this. #science
