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.

Lay Siege To The Doghouse!
Right after you build your own working medieval catapult or trebuchet. All you’ll need is glue, scissors and a steady hand (plus a small bag of marbles or rocks or something as a counterweight for the trebuchet) to construct these wooden, Canadian-made siege engine kits. The catapult stands 6” tall x 5” wide x 10” long and will toss assorted stuff 15 feet or farther, depending upon the stuff. The finished trebuchet will be 26” long x 18” wide x 24” tall and will propel small objects (meatballs?) 20 feet or more. Both include detailed instructions and are great resources for STEM activities. Note: Please don’t propel small mammals, and please don’t put anyone’s eye out.

Leo, You’re Our Model
Leonardo DaVinci didn’t work so hard to come up with his brilliant devices just so we could forget about them 500 years later. Get this DaVinci pack of (4) wooden model kits of his machinery and understand the genius. The classic catapult, approx 9” tall, uses the tension from (2) bent arms to power the spring and throw a clay ball over (13) feet. The ornithopter has an approx 24” wingspan and comes with a 15th century crash test dummy. The aerial screw helicopter has a canvas canopy and measures approx 15” tall on a 9” square base when complete; and the trebuchet, another launcing device, measures approx 12-3/4” x 4-1/2” and 24” tall. Of course, it comes with a clay ball to shoot, too. Most for ages 9+.
