Can You Build a Working Cannon Out of Duct Tape? | MythBusters
In this episode of MythBusters, the team tests whether a fully functional cannon can be constructed using only duct tape instead of traditional materials, ultimately confirming that it can withstand the explosive forces required to launch cannonballs, albeit with reduced performance compared to a steel cannon.
Watch on YouTube ↗Key takeaways
- Duct tape can be used to construct a functional cannon, demonstrating its strength and versatility compared to traditional materials.
- The duct tape cannon achieved an average range of 336 ft and a speed of 160 mph, showing performance nearly identical to a PVC cement cannon, which had an average range of 346 ft and speed of 179 mph.
- The team confirmed that the duct tape held up under explosive conditions, successfully launching a potato without the cannon exploding.
- To test the limits of duct tape, the team created a strength gauge that withstood the explosive pressures of a cannon, proving that 1-inch thick duct tape can handle significant forces.
- The final duct tape cannon was constructed with a 2-inch thick barrel to prevent collapse under pressure, showcasing the necessity of careful design in explosive experiments.
- Experiment with duct tape in small projects to understand its strength and versatility before attempting larger builds like a cannon.
