Building our April Fool’s Day project, the MarshMallowMatic, was a fun project but not without its fair share of trial and error. When heating flammable materials with an oxy-fuel torch, the biggest challenge is simply not setting them on fire.
In the video above — one of our first trials, before we had figured out how far away to position the flame — we wondered what would happen if we tried to “evenly” roast a marshmallow… with predictable results. Let’s just consider this an outtake.
Introducing the MarshMallowMatic: the world’s first dedicated CNC marshmallow toasting machine— capable of custom marking and toasting of marshmallows under robotic control.
The MarshMallowMatic is built from a special, modified version of our Ostrich Eggbot kit, fitted with a compact oxy-fuel torch:
The oxy-fuel torch can produce a 1″ (2.5 cm) long flame, with temperature in excess of 5000 °F (2760 °C). “And wow, can it toast marshmallows!”
Woo-hoo! We just got Cooking for Geeks
in the mail. You can view it as a cookbook that takes time to delve into the science of the recipes or a food science book with demonstrative recipes. Or maybe an introduction to everything that food geeks know about, but everyone else wishes they did. It also has a series of interviews with geeks, chefs and scientists– including us, but I’m not sure which of those categories we fit into. Regardless, we enjoyed talking with Jeff about the book and are happy to see it out in print!
The cover design with splatter marks and stains means less worry when it gets spilled on in the process of cooking (not that I’ve ever worried about that with any of my other cookbooks).
Most pages have ample room for margin notes, which is something I’m fond of for recipe alterations. It flops open on the counter well, too.
We got a nice shoutout from Jeff on NPR’s Science Friday
last week for the laser cut pie crust from our Apple pie
, which is featured in the book along with our electrocuted hot dogs
. Thanks, Jeff, and congrats on getting the book out there!
With a little help from a square springform pan, you too can have an Apple apple pie for dessert!

One of the things that we kept hearing as a comment about our CNC toast story is that we really should be printing the Virgin Mary on grilled cheese sandwiches, or something like that.
As it turned out, by the time that we actually wrote about our toasting, we had already moved on to bigger and (probably) better things, like printing sugar. Since we were rushing to get ready for Maker Faire, we didn’t get a chance to make more creative toast.
But, Maker Faire has come and gone, and we’ve finally got our machine reassembled, and so here we are toasting again. Believe it or not, this is actually a step in the right direction for CandyFab as well, because these were printed at 20 DPI, already an improvement with four times as many pixels as our previous batches at 10 DPI. These four Flying Spaghetti Monster images on toast are adapted from the original artwork in pencil, by Bobby Henderson.
Oh yeah, and I put one of them on eBay. =D
In February we gave a sneak preview of our project to construct a home-built three dimensional fabricator. Our design goals were (1) a low cost design leveraging recycled components (2) large printable volume emphasized over high resolution, and (3) ability to use low-cost printing media including granulated sugar. We are extremely pleased to be able to report that it has been a success: Our three dimensional fabricator is now fully operational and we have used it to print several large, low-resolution, objects out of pure sugar.
