I Built a GIANT CRAYON Fish Tank in 48 HOURS! (Self-Cleaning DIY)

A teacher texted me to build a CRAYON Fish Tank for her classroom... and I only had 48 hours before a flight! This is the race to build a complete, self-cleaning aquarium for 20 kids. In this video, I share the entire process of designing and building this colorful, kid-friendly fish tank from scratch. Watch as I 3D-print giant hollow crayons, create a (patent-pending!) modular planting system to keep the water clean, and assemble it all just in time for a classroom surprise. We even had a major disaster when the crayons wouldn't sink! 🐠 See the full build: – How I 3D-printed giant crayons to serve as fish hideouts – Designing the self-cleaning, low-maintenance filtration system – A building DISASTER (the crayons floated!) and how I fixed it – Harvesting live aquarium plants from my greenhouse – Delivering the finished tank and surprising 20 kids – The final Betta fish reveal!
