We had a great evening of physics demos and discussions on Wednesday night. Thanks to Marty (CHS), Dave (CHS), Caleb (CHS), Josh (PMSA), Kunal (HPHS), Bryan ( GBN), Mark (PHS), Mike (SHS), and Sasha (Northwestern University) for sharing. The hosts were excited to give away 3D printed models of the “Accurate PVC Launcher”, “Moment of Inertia Spinner”, “Cheap Pulley”, and “Adjustable Frequency PVC Horn”. All of the designs were built using the free website www.tinkercad.com.
If you have access to your own 3D printer, you can print your own!
