Description
There are three known materials that readily undergo fission, allowing their use as a base for nuclear fuel: uranium-235, a naturally-occurring but uncommon isotope; plutonium, created from irradiated natural uranium; and uranium-233, produced from thorium. Of the three, uranium-235 and plutonium feature heavily in the modern nuclear industry, while uranium-233

There are three known materials that readily undergo fission, allowing their use as a base for nuclear fuel: uranium-235, a naturally-occurring but uncommon isotope; plutonium, created from irradiated natural uranium; and uranium-233, produced from thorium. Of the three, uranium-235 and plutonium feature heavily in the modern nuclear industry, while uranium-233 and the thorium fuel cycle have failed to have significant presence in the field. Historically, nuclear energy development in the United States, and thorium development in particular, has been tied to the predominant societal outlook on the field, and thorium was only pursued seriously as an option during a period when nuclear energy was heavily favored, and resources seemed scarce. Recently, thorium-based energy has been experiencing a revival in interest in response to pollution concerns regarding fossil fuels. While public opinion is still wary of uranium, thorium-based designs could reduce reliance on fossil fuels while avoiding traditional drawbacks of nuclear energy. The thorium fuel cycle is more protected against proliferation, but is also much more expensive than the uranium-plutonium cycle in a typical reactor setup. Liquid-fueled molten salt reactor designs, however, bypass the prohibitive expense of U-233 refabrication by avoiding the stage entirely, keeping the chain reaction running with nothing but thorium input required. MSRs can use any fissile material as fuel, and are relatively safe to operate, due to passive features inherent to the design.

Toy hacks modify commercially available toys to be more easily used by people with motor disabilities, and donate them to schools, families, or toy libraries. Switch-adapting a toy adds an audio jack to allow an assistive technology (AT) switch to be plugged in. Switch-adapted toys help children develop essential skills through play. Hacking toys is helpful because toys that come with AT switches are often significantly more expensive than their unadapted counterparts. Toy hacks are also an opportunity to teach and practice engineering skills such as soldering and technical problem solving. Many resources are available online to assist makers with hosting toy hacks, but most of them lack information on holding the event. To fill this gap, the authors created a toy hack guide website, drawing from experience hosting two toy hacks. It walks users through steps like choosing the size of the event, the materials that need to be purchased, and connects them to other existing resources. In the future, it will be used to help people host more successful toy hacks.
