DIY Soft Robotic Tentacle

During my gap year I experimented with ways to introduce soft robotics to interested students. This project is an easy and affordable way to demonstrate the nature of soft robotics. The molds are made from ballpoint pens, only take a few minutes to make, and do not require any careful measurements. A single trial size unit of Ecoflex 00-50, contains enough rubber to make over 40 tentacles, making it an ideal project for schools or STEM camps. The process is open sourced and detailed in an Instructable ( with over 24K views and demonstrated in a YouTube video with roughly 58K views.
