Help Us Make A Cloud Chamber

This March, as a special project for our Make Afternoon social, we’ll be making a cloud chamber.  Invented in 1911, it’s a tool that makes cosmic particle visible to the naked eye as they travel through a cloud of alcohol vapors. We’ll be able to identify protons, electrons, and many other particles by the trails they leave as they travel through the mist:

We should have all the materials we need to create this chamber, but check out the directions if you’d like to help us put it together. And, as always, be sure to RSVP! 


Would you like to sign up for a monthly donation? 

Donations help us rent spaces to make more cool stuff in (and keep us in tea!)

Our First-Ever Make Afternoon Is This Saturday!

tools

Join Spanning Tree for our first ever Make Afternoon on Saturday, January 17th.  We will be meeting at 1:00 pm in room A-9 of the Martin Luther King Jr. Memorial Library for an afternoon of making, crafting, and getting to know each other.

This is the perfect place to finally finish those knitted mittens, put the finishing touches on your personal website, or learn how to solder. Bring a project to work on or just yourself. We’ll have tables, snacks, plenty of outlets, and — if our plans work out — wi-fi.

Additional equipment available for use: a sewing machine, extra knitting needles, a button-making device, a soldering iron and glitter glue. (If you’d like to bring artwork for buttons, try to fit it within a 0.875″ diameter circle — but leave plenty of margin around that, it will be set up to make one-inch-diameter pin-back buttons. )
