Do you want to get into music? Have a ukelele you've always been meaning to learn how to play? In this class we'll start at the basics, and learn a bunch of ukelele techniques!

Come watch us use liquid nitrogen to shatter fruits and rubber balls, freeze bubbles, and levitate chalk! We’ll be making liquid nitrogen ice cream (and you can follow along at home by substituting the liquid nitrogen with salt, ice, and elbow grease). Along the way, we’ll also explain the science of liquid nitrogen and show you a bunch of cool (get it?) demos!

Did you know that lasers could be used by satellites to talk to each other? We could use a laser on the ground to communicate with International Space Station (in fact, NASA is working on a program like this!). In 2016, NASA put laser communications system on a satellite orbiting the moon, and used it to talk to Earth. Both SpaceX and Amazon's satellites intend to have lasers for communications. In this class we shall learn how space-based laser communications work, what hardware is required, what makes it difficult / better / worse than radio frequency communications. We shall learn about technology behind current laser space missions and will talk about planned future missions.

Fusion energy has been the great dream of the world for nearly a century, but it often feels like a pipe dream. No radioactive waste, 0 risk of meltdown, 100s of millions of years worth of fuel on Earth alone, high power density, it's on when you need it (no need for batteries). But why don't we have it? Or do we? This class will give you the background to understand how fusion works, what the current state of fusion research is, and where it's headed. Focus will be on MIT's initiative, and on giving you guys reasons to get hype! Spoilers: there are a lot of them :)

Stuck in isolation? Looking to upgrade your doomsday homemade food skills? Come join a group of quarantined students and learn the theory and practice of safe food storage, starting an indoor herb garden, fermenting foods, pickling foods, and making cheese, yogurt, and tempeh. You'll get a list of ingredients and materials beforehand so you may follow along, or just tune in, ask questions, converse, and chill in this interactive class. There are a wide selection of projects, and while we don't expect you to follow every one, we do hope there are some that only need materials you already have in your everyday kitchen. Our planned course road: Jun 11: Intro & Herb Garden Jun 18: Kitchen Care & Pickling Jun 25: Fermentation Aug 01: Cheese & Yogurt Aug 08: Tempeh Aug 15: Grand Dinner & Closing With regular checkups of the state of previous projects!
