Here's what you'll need to dress up as Chien-Shiung Wu for Halloween!
To complete your costume, you'll need to make a life-size atomic model - essentially you'll be the nucleus surrounded by orbital paths for electrons! To make this awesome STEM project, you'll need:
- Two hula hoops: Amazon link (this one is a set of two!)
- Ball pit balls: Amazon link
- Zip ties or tape
- Wedge one hula hoop into the center of another hula hoop so that they create an "X" shape at the top and bottom. Secure the "X"s with a zip-tie or tape. This will create the orbital path for your electrons.
- Cut a hole out of the top and bottom of a ball pit ball with scissors and then cut a slit along one side of the ball from the top hole to the bottom hole.
- Wrap the ball pit ball around each orbital path (hula hoop) and secure with tape. You can use as many balls as you like, but make sure you know which element has that number of electrons! Use the periodic table at ptable.com for reference; remember that an element's number of protons designates its atomic number, and in general, it's number of protons will equal that of its electrons.
- When you're ready to dress up, step into the center of the hula hoops and rest one of the "X"s behind your head, and the other in front of your legs.
For your trick-or-treat bag, paint the symbol for uranium - which Wu worked to separate into isotopes with other scientists on the Manhattan project - from the periodic table! You can purchase a canvas bag to paint at Amazon.
