My Coke runneth over

They say you can’t un-break what’s broken, un-see what you’ve seen or put the toothpaste back in the tube. But can you un-shake a can of soda? More to the point, does tapping the top, slapping the sides or flipping the can end-over-end make a difference?

I’ll tell you what I found out, but some of you might not like the answer ….

Does Tapping a Soda Can Prevent it from Foaming Over?

In a microwave, still waters run deep – and dangerous

Tick-tock.

In case you’re wondering, yes, microwaves are magic and, yes, they are trying to kill you. Take that seemingly innocuous cup of water that you just heated for your afternoon tea. Shouldn’t that be bubbling by now? After all, you nuked it for an awfully long time.

Come to think of it, what do you really know about that microwave?

Times are tight. Many of us feel trapped between the food we can afford and the medical bills that we can’t. As obesity and its related illnesses – including heart disease, high blood pressure and diabetes – grow more prevalent, ballooning healthcare costs threaten to shrink our wallets.

Most of us know that we need to take charge of our own health, but how? And where will we find the time? We’re busy, frazzled, mired in bad habits and assailed by late-night ads for fad diets, pills and gimmicky workout machines. Meanwhile, most of us have no idea how our caloric intake stacks up to our daily burn.

Surely, this is a job for a gadget.

Can a watch help you lose weight?

Wristwatches: Is it time to disband?

Every few years, someone writes an article about how kids today don’t know what a rotary phone is, or have never heard of a cassette tape, or are losing the ability to spell or write cursive. I still remember, years ago, when one study revealed that not only did today’s youth not know how to wind a watch – they didn’t know what the phrase meant.

As someone who was required to be able to understand references to technology, art and entertainment dating back to my grandmother’s time, I take these articles with a grain of salt. That includes the recent spate of pieces in blogs and news outlets declaring the death of the wristwatch. Sure, we all have cellphone, and there are as many clocks in my kitchen as appliances, but – as I point out in this misleadingly named article – the watch has yet to tick its last tock.

Why don’t we wear wristwatches anymore?
