Introduction There is a medicinal ointment popular in Hong Kong called 白花油 (“White Flower Oil”) that produces a cool, minty feeling when rubbed on the skin and is used as a pain and itch reliever. (A similar product called 风油精 (“Wind Oil Essence”) is used in Mainland China.) Interestingly, one of its main ingredients, which…

Introduction and Rules 24 is a card game in which players try to use the basic arithmetic operations and each of four numbers exactly once to get the number 24. I play the game with my friends as follows: in each round, 4 cards are dealt face-up, and the first person to yell out a…

Introduction I have some dirt,I have some sand.Uh! Green sand. I poured zinc,into the green sand,Uh! Sand casting. (The PPAP song went viral when I was in elementary school and the funny lyrics made an impression on me. So here we are.) My previous attempt at casting focused on casting a detailed model with no…

The other day, as a result of playing with gasoline, I got some second-degree burns. Eight years ago, in preparation for a backpacking trip to Sword Lake, my dad bought a 1-gallon can of Coleman Fuel (a petroleum distillate similar to gasoline but without the engine-performance-enhancing additives), to fuel his Coleman 442 pressure stove. After…

Introduction For no reason at all, I decided one day to make one of those top-lit updraft (TLUD) wood gasifier stoves that are a common design for DIY small biomass-fueled stove projects. The design has been researched pretty extensively and is viewed as a promising stove design to replace dirty and smoky biomass stoves commonly…

Finding no other similar resources online, I created this printable list of the keyboard shortcuts in Ubuntu. There’s only one change from the default shortcuts: I’ve set Ctrl+Space to be the shortcut for playing/pausing media playback. If you like you can edit the provided .odt file. Here’s the infinitely low-tech way I got all these…

Introduction Where I live, the soil has a very high clay content, so I’ve tried a few times in the past to turn it into some usable clay-like material. Clay is easier to work with than metal and wood, can endure high temperatures unlike plastic, and is more durable. In my attempt to cast zinc,…

I created a tree map of Jane Lathrop Stanford Middle School for my Broadcast Media class in 8th grade, but it was never published. As I was doing research for that project, I stumbled upon the Canopy Tree Plotter, a tree map of Palo Alto, though since it didn’t list the trees at JLS, I…

Introduction I’ve been trying to refine my backyard soil into some workable clay in order to further my metal casting project. As you can imagine, this comes with some challenges as not all clay, even when purified, is suitable for making stuff. In the case of the clay in my area, it’s very sticky and…
