DAVINCI TREBUCHET KIT
Leo Vinci Kits
Return with us now to those thrilling days of the 15th century, when Leonardo was designing stuff you wouldn't have thought of even if you'd paid attention in class and applied yourself. You choose from these wooden models of his genius designs. His unrealized aerial screw (think helicopter) stands approx 15" tall on a 9" square base and has a canvas canopy. Includes a 12-page manual and all the parts. For ages 9+. You’ll need glue, scissors and a ruler. The trebuchet (think catapult) is based on his original 1482 design, stands approx 24" tall x 12-3/4" x 4-1/2" and comes with all the parts, including a clay ball to launch at your favorite model castle, or your sister. Includes an 8-page instruction book and is for ages 12+. Bring glue, scissors, a ruler and some small clamps. His wooden armored tank, for ages 8+, will be about 8” across and 6-5/8” tall when you glue the (87) pieces together. Great resources for STEM activities.
