Da Vinci's Bombard
Build a tabletop bombard! Leonardo da Vinci designed this mighty cannon, a medieval artillery weapon, in the 15th century.
Send projectiles up to 15 feet! Each model is fully functional; the kit comes with 6 projectiles plus 6 paper targets.
Everything you need to assemble each model in 1-3 hours: laser-cut wooden components, rubber bands, sandpaper and clear, simple instructions. No special tools are necessary.
