I am thrilled by this new quirky podcast, that is both fictional and factual. In “Everything Is Alive,” the host interviews inanimate objects, like a pillow or bar of soap. By any logic, this should be flat-line boring, but unexpectedly, each episode is brilliant, funny, informative, and remarkable. Other than the fact the objects talk, everything they say is true. Just listen to the can of cola talking about his life in the first episode and you’ll be hooked. — KK

Hiking poles give me two extra legs. They are most useful going downhill, over uneven or wet terrain. I bring them wherever I hike, especially when I travel, because I use a collapsible set from Black Diamond that folds up to less than 14 inches (36 cm). That not only fits in carry-on luggage, it will also hide away in a day pack, so I can take them out only when needed. The $75 Distance Z-Poles are lightweight aluminum, unfold in a second, and are very rigid. You can get featherweight carbon fiber if you want to pay more. — KK

Last week my friend texted to tell me that 4 planets were visible and I should go outside to check them out. I was only able to see 3, but I found them quickly with the beautifully designed SkyView app ($1.99, also on Android). I just held my phone up to the sky and SkyView pinpointed where they were precisely. For the occasional stargazer this app is more than enough. — CD

I prefer these flat microwave covers ($7) to the larger lid-type ones. They block splatters just as effectively, but take up less space and are easier to wash. — CD

My sister texted me and told me to watch the YouTube series called The Reassembler. I was 7 minutes into an episode when I texted her back: “This is the greatest thing I’ve ever seen on YouTube.” I don’t even think I was exaggerating. Each episode starts off with host James May in a workshop, standing over components of something that has been taken apart (like a lawnmower, an electric guitar, or a model train set). He then puts it back together, narrating as he does so. As he says in the introduction, “it is only when these objects are laid out in hundreds of bits and then slowly reassembled that you can truly understand and appreciate how they work and just how ingenious they are.” — MF

I’ve taken a deep dive into Bitcoin and blockchains for the last couple of years and have read about a dozen books on the subject. Bitcoin for the Befuddled is the book I recommend to anyone who asks me where to start. It does a great job of explaining how Bitcoin works, going into detail without being overly complex. — MF

I really love my all-electric Chevy Bolt which gets 240 miles from an overnight charge in our garage. Its immense power and acceleration is intoxicating. Unexpected bonus: silence inside. Also the car is basically an iPhone accessory. There a few downsides: it has a boring generic style and the 4-door, 5-passenger hatchback has only a tiny trunk. Otherwise, functionally I get 95% of a Tesla at about half the price. — KK

If you lose or forget to bring a cable, adapter or charger, check with your hotel. Most hotels now have a drawer full of cables, adapters and chargers others have left behind, and probably have the one you are missing. You can often claim it after borrowing it. — KK

Most tubes of toothpaste, hair gel, and lotion have sharp corners on the crimped end. The sharp corners easily slice through the plastic bag I keep my gels and liquids in when flying. I started snipping the corners with nail clippers. I even fillet the corners of tubes at home, to prevent them from jabbing my fingers when I reach for them in a drawer. Just be careful not to cut the corners so much that it causes a leak. — MF

On a recent trip to Tokyo, I brought along the Sea to Summit Travelling Light Day Pack ($33). It weighs 2.4 oz (my iPhone 6 Plus weighs 6.2 ounces) and zips up into a bundle smaller than my fist. But it holds 20 liters of stuff, and I used it every day to carry water, snacks, sweaters, an iPhone charger, a portable wifi, groceries, and things my wife and I bought while walking around. The material feels indestructible. — MF

You aren’t allowed to bring a bottle of water past airport security, and the bottled water sold at airport convenience stores is expensive. But many airports now have filtered water dispensers. I keep a collapsible water bottle in my travel bag. It rolls up to a tiny size and weighs nothing. Free water, what a concept! — MF

This car pillow makes long drives, slow traffic, and neck pain more tolerable. The material is so soft and it’s so nice to lean my head back on this after work. When my husband drives he can easily adjust it to his height. — CD

I recently visited my grandmother in Mexico and the first thing I packed was my pStyle, which helps women pee while standing. It was the perfect travel tool for Mexico, where most public bathrooms have no toilet seat and you have to pay for toilet paper. There was no mess, easy to use and I just attached it to my purse in one of these discreet carrying cases. — CD

This eBags toiletry bag is the perfect size to fit all essential travel toiletries plus a lot of my makeup. It has four compartments and stays pretty flat, so I can slip it into my large tote if I need to. My favorite feature is the hook for hanging which is great for hotels with little counter space. — CD

What3Words divides the world into 3 x 3-meter squares and gives each square a unique, unalterable sequence of three random words. For instance the location of my writing desk is “smile.rocket.gates”. This global address is really handy for sending a delivery person to the right part of a building, or meeting someone on at trail head, or locating a home in the large parts of the developing world that have no operational address. It’s better than a lat/long sequence because you can remember it. Works in multiple languages. The phone app version integrates into Google maps, etc. — KK

I’m not surprised that Google has been tracking my every move since 2009. I’m sure I allowed it when I accepted its terms of service at some point. What is surprising is being able about to browse this timeline of my location on a world map. This Google page has day-by-day reports of you where you where, the paths you traveled, the restaurants and stores you visited, and any geotagged photos you took on any given day. You can even edit the information if its incorrect. Wow! — MF

Here are 12 really great tips for using Google Maps on your phone. How to share your current location, or share your trip progress, remember a parking space, invoke street view, estimate trip duration by departure time, or send a map search from your computer to your phone. I had no idea I had these powers. — KK

Part 1: Here’s an easy way to approximately convert Centigrade to Fahrenheit: “double the Centigrade temp, subtract the first digit of the result from the result and add 32.” Example: 16 C = (32-3)+32 = 61 F. (This tip is from Fodor’s Travel website.) — MF

Part 2: Recomendo reader Don wrote to tell us, “Your Centigrade to Fahrenheit conversion works ‘sorta’ as long as the result of doubling the C number is a two-digit number. I’ve always doubled the C number and subtracted 10%, then added 32. Most folks can figure out 10% and subtract it. Also, this doesn’t result in an approximation, but the correct result.” — MF

Part 3: The US is basically the only country in the world not using metric. It’s not that hard to learn a rough sense of how many kilometers in a mile, or pounds in a kilo. But it is very hard to convert temperatures between Centigrade and Fahrenheit. The solution is to convert all your thermometers to Centigrade: on your phone, in or outside of your house, on websites. Have any digital device display only Celsius, so you can’t cheat. In about a year, you’ll have a reliable and native sense of what’s cool and warm in degrees C. This is supremely handy if you travel anywhere outside of the US. — KK

I stow PDF scans of my passport, visas, itinerary and key travel docs in my Dropbox, which show up in the Dropbox app on my phone so I always have them in case of loss while traveling overseas. — KK

The cheapest bargain of any overseas vacation is the $25 for the travel guidebook, so I always get the latest version. And I have no qualms about cutting it up. I get the large country-scale guide, and then with a razor blade knife I excise only the portions I could possibly use. Then I staple and bind with clear packing tape for very durable, and lightweight, thin booklets. — KK
