Wide Mouth Canning Jar Accessories

I was planning to write a review of the Norpro Wide Mouth Funnel, because it’s one of my favorite kitchen tools and has revolutionized my food storage process. But then I realized the funnel is a small a part of a larger system of jars in my kitchen. The iconic canning jar — better known […]

Rinnai Direct Vent Wall Furnace

I’ve had a similar Rinnai direct vent heater similar to the newer model for over 3 years. It replaced an older Italian made direct vent heater that was poorly designed. The Rinnai has a digital thermostat and uses a piezo lighter. It comes on reliably and there’s no pilot light at all. It direct vents […]

T-Reign Retractable Gear Tethers

I use the T-Reign gear tether to keep my stuff within reach and ready for use. I received a gear tether as a gift and quickly had to order a couple more for other uses. I keep one for my EMT shears clipped to a D ring in a cargo pocket. The shears are ready […]

SuperMemo + Anki

In high school, I tried to learn Spanish, and failed. In college, I tried again, and failed again. Then, in my thirties, I discovered SuperMemo, and within a year I had memorized thousands of Spanish words and phrases and was finally on my way to speaking Spanish. SuperMemo is software premised on the idea that […]

Dorkfood DSV Temperature Controller for Sous Vide

Works flawlessly, controlling temperature to one degree. Using it with my 25-year-old Proctor Slo-Cooker (Original cost $19). Best thing so far is 48-hour short ribs. Cooking them at 140 degrees for two whole days makes the best tasting beef dish I ever had. The meat is totally different texture than what a braise gives you […]

Camelbak Eddy Bottle

At night I wake up with a dry throat and reach blindly for water. I used to knock over glasses and cups until I found this two years ago. It’s basically a sippy cup for adults. It has rubber mouthpiece that doesn’t open until you squeeze slightly with your lips, so no dribbling, and it […]

Science Fair Handbook

* Developing a Hypothesis After students have designed an appropriate question, they must turn that question into a hypothesis. A hypothesis is an educated guess, a statement of how the scientist thinks the experiment will turn out. It is a prediction, based on the best available information, of what the scientist believes will happen at […]

Ammo Can Organizer

I can’t believe it took me this long to find this set of three organizer trays that stack neatly inside a common .50 caliber ammo can (available at any military surplus store, or here on Amazon). The three sturdy  trays contain a total of 22 compartments of varying sizes and can be stacked in any order. […]

YouTube: An Insider’s Guide

Sample excerpts: Low numbers can be frustrating for new bloggers and video makers. It’s difficult to invest hours into making a video, only to upload it and find a day later that only some 10 or 12 people have watched it. Trust me when I say this, though — we have all been there. If […]

What’s in My Bag? – Ryan Holiday

I travel a lot. For work mostly. But I love it because I get a lot of work done on the road. Whether it’s reading books, or writing or catching up on email, I tend to have bursts of productivity while I am traveling and then I get to enjoy myself on the trip. This […]
