Gallium is a metal that melts at 86 degrees F. It's more fun than playing with mercury, and probably safer, too (it *will* temporarily stain your skin gray though, because it's "wet" when liquid and will adhere to the crevices of your skin). My daughter's friend brought some over a couple of years ago, and it was such a hit at our house that we had to get some of our own. This 20 gram sample is on Amazon.

We had one of these in the MAKE magazine office for years. I think the shrimp's name was Fred. Amazon has the small one on sale for $44, which is an all-time low price.
Read the restEcoSphere is a completely closed, balanced, glass ecosystem. Inside each EcoSphere are shrimp, algae, and microorganisms in salt water. Because the EcoSphere contains everything it needs to thrive, you never have to feed the life within, or change the water. All that is needed is a comfortable room temperature (between 65 and 80 F) and a source of light.
I was recently interviewed about the weekly Recomendo newsletter I write with my Cool Tools colleagues, Kevin Kelly and Claudia Dawson. Here's an excerpt:
What is the goal of your newsletter?
To give our readers a weekly list of 6 things we love — travel tips, books, TV shows, clothes, tools, websites, podcasts, and so on. We want people to be able to read the entire newsletter in 90 seconds or less, with no fluff or wheel spinning.
How do you create your newsletter?
We have a shared Google Doc where the three of us write brief reviews of things we like. Once a week, Claudia goes in and selects six items from the doc (two from each of us) and puts them into the weekly newsletter, which gets sent out on Sunday morning.
Speaking of the creation process, Recomendo always has super cool and useful recommendations. How do you go about selecting what goes into the newsletter?
Speaking for myself (this is Mark), whenever I become aware that I am really appreciative of something (like a phone service, a useful app, a good snack to travel with) I add it to a running list I maintain on workflowy.com. Once a week or so, I will go through that list and write brief recommendations of a few of the items on the list.
How many subscribers do you have?
As of 29 June 2017, we have published 49 weekly issues and have 11,528 subscribers. Once a month or so, we mention the newsletter on our personal social media accounts, on Cool Tools, and on Boing Boing. Read the rest

Frixion Erasable Blue Gel Ink Pen ($13, 3 Pack) "So, this pen is not actually marketed as a disappearing ink pen. It’s marketed as a Frixion Pen, and its intention is to be an erasable pen — it’s a normal-looking pen and on the back of the pen is this sort of rubber or plastic nib. And if you write with the pen and you rub the nib over the ink, the ink goes away. But, the true nature of the pen is that it's heat activated. So, if you heat up the ink, it disappears. That could be with the nib that's on the back of the pen or that could be with the flame from a lighter or that could be in a microwave. So, basically, what you have, is you have a pen that writes with ink that you can make disappear with fire. And that is a pretty cool tool to me. … One of the cool things about it is that you can use it sort of as a fun science thing to do with kids because, you don’t necessarily need to use fire.

Once a week, Kevin Kelly, Claudia Dawson, and I send out a weekly newsletter that gives you 6 brief personal recommendations of cool stuff. We have 11,821 subscribers. Here's issue #54. Get the Recomendo weekly newsletter a week early by email.
Getting good stuff on craigslist: This brief, succinct blog post has great advice on how to find what you want (at least with used furniture) on Craigslist. For instance, don’t forget to search for common misspellings of your target. These tips match my experience in buying used tools on Craigslist. — KK
Better book finder: Kooba is a fun option for finding the next book on your reading list. Just type in a title you like and you’ll get an interactive graph of suggestions. You can keep adding book, remove any you don’t want or start clicking to create a deeper web of recommendations. — CD
Menu reader: This $8 magnifier is the size of a credit card, and as thick as a stack of six quarters. The lens is 1.75" square and there’s a smaller round lens in the corner. A button on the side turns on a bright LED. I’ve taken to carrying it in my pocket. It comes in especially handy for reading menus in dark restaurants. — MF
Workshop tip: When mixing epoxies, resins, goops, paints, glues, I always need to dispose of the gunked up mixing container afterwards. I try to hoard used take-out containers and paper cups yet run out. By far the best solution is to use flexible silicone mixing bowls. Read the rest
A few months ago my friend Joshua Glenn asked me to contribute a short piece to a series of true stories "about objects that are lucky, magical, kept on your person or close by at all times." The series is called Talismanic Objects. You can read all the stories at Hilobrow. Here's mine:
Read the restAs a little kid in the 1960s with limited access to television, my role models were my friends’ big brothers. My friends certainly weren’t role models — they were dweebs like me. And grown ups — they might as well have been a different species, with a way of thinking that made them impossible to relate to. Big brothers were still kids, but infinitely more sophisticated and wiser than 6-years-olds like me (who big brothers regarded with indifference at best and as sticky-fingered pests at all other times).
It was a thrill to walk past a big brother’s open bedroom door and sneak a glimpse in their rooms to find Aurora Monster Models, Mars Attacks trading cards, black light fluorescent posters, MAD magazines, Green Hornet’s Black Beauty model car, Cowsills LPs, Lost In Space View-Master reels, Super Balls, Sixfingers, and Ka-Bala game boards. To me, these treasures will forever be imbued with big brother mojo.
I have a talisman that I can use to summon big brother mojo. It’s a Martian Fink ring — a little armless vinyl creature with pointed ears, antennae, square feet, and a long tongue curling from its leering mouth. It’s attached to a plastic ring so I can wear it on my finger (I don’t).
J.L. Lawson & Co makes tops, spinner coins, and other hand-machined products.
Their latest thing is the Tempus Spin Coin, and has been successfully funded on Kickstarter. It's still available in .999 silver, bronze, and copper.
For those of you that are interested in spin times, my average time ranges from 7-9 minutes. Considering the art isn't balanced, the spin is fairly balanced but, keep in mind, this coin wasn't intended for perfect spinning. It's more to help keep you entertained at the local bar.
Paul Abueva is a residential contractor. He shared the contents of his tool belt at Cool Tools (a web site I run with Kevin Kelly and Claudia Dawson).
I am a residential contractor who does remodeling and repair work, so I carry tools that that are useful to a variety of trades work. Over the years I’ve put together what I believe to be a perfect compromise between weight and function. Read the rest
In the latest episode of the Cool Tools podcast, Kevin Kelly and I interviewed Alan Henry, editor in chief of LifeHacker. He's also a recovering physicist, music lover, and self-proclaimed lover of dorky and niche hobbies. Alan told us about his favorite headphones, a cold brew coffee maker, a mechanical keyboard, and a web-based smart to-do list app.

Let's take the path less traveled for some holiday gift giving. Two brothers well known in the world of magic and cardistry , Dan and Dave Buck, have a number of enterprises going, including a website called Art of Play . While its nucleus is the sale of unique decks of playing cards, the site has expanded greatly under the guidance of Adam Rubin, the "Director of Puzzles and Games."
We travel the world in search of objects designed to dazzle the eyes and fascinate the mind. From luxurious playing cards to ingenious puzzles and stimulating amusements—each beautiful item in our collection holds a whisper of mystery, brimming with potential for surprise and delight.
25 Days of Christmas Extravaganza! Whatever you celebrate this December, we're honoring you and the ones you love with our 25 Days of Christmas extravaganza. Every day through December 25th we will offer either a free gift or an exclusive item, such as a rare deck of playing cards. Offers are limited to one day only. To take part, just be sure you're subscribed to our newsletter.
I'm personally not much interested in fancy decks of cards—I do my card tricks the old-fashioned way, using Bicycle Rider back cards from the U.S. Playing Card Company. But if, for example, you're a fan of Neil Patrick Harris (who also does magic in addition to being able to sing, dance, act, emcee, etc. and so on) then you might find this special deck interesting.
