Balloon Speed Boat

Here's a video of it in action! https://youtu.be/EtTMcURcMaU A self-propelled boat that uses a balloon for propulsion. The top of the boat features a standard balloon attachment, but ziptying it for optimal use is recommended. You can also scale down the model to fit your printer's capabilities, but then you'll likely need to secure the balloon with zipties. Once the balloon is securely attached and inflated by blowing through the hole in the back, the boat will begin to move forward when submerged in water. To enhance performance, adding weight to the back of the hull using BBs or similar objects and gluing them before printing the deck is advisable. This ensures that more of the back hole remains underwater during propulsion.
