Hi Andrew,

Building a Spark Gap Radio Transmitter can be a fun and educational project. There are many resources available online that can guide you through the process. Here are a few sites that you may find helpful:

1. Make: In this article, you can find step-by-step instructions on how to build a Spark Gap Radio Transmitter using easily available materials. It also includes a video tutorial to help you understand the process better. https://makezine.com/projects/build-a-spark-gap-transmitter/

2. Instructables: Here, you can find a detailed guide on building a Spark Gap Radio Transmitter with pictures and diagrams. It also includes a list of materials and tools needed for the project. https://www.instructables.com/id/Spark-Gap-Radio-Transmitter/

3. YouTube: There are many video tutorials available on YouTube that demonstrate the process of building a Spark Gap Radio Transmitter. You can watch these videos to get a better understanding of the project. https://www.youtube.com/results?search_query=spark+gap+radio+transmitter

Remember to always be safe when working with electrical components. Also, make sure to do proper research and follow the instructions carefully. Good luck with your project!
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
