Leonardo Da Vinci Helicopter

One of Leonardo’s most iconic images, the Aerial Screw (also known as the Helicopter) illustrates the ingenuity of da Vinci, and indicates (along with many other drawings!) his obsession with flying.

While this 15th Century (!) idea may never have got off the ground, for some basic technical reasons, it gave us an insight into the different ways in which Leonardo considered the challenge of human powered flying, and defines him as an inventor well ahead of his time.

Trebuchet

Considered by many to be the most powerful and destructive of all the siege engines, the trebuchet took many forms throughout the Medieval world, hurling huge rocks, giant fireballs and even diseased animals at (and into) castles.

This model, based on the Warwolf, is a tabletop working replica of a trebuchet made in the 13th Century.

Standing 26 inches (67 cm) tall by 18 inches (48 cm wide) this model will shoot balls of plasticine (included) over 20 feet! Please be careful of what (or whom) you take aim on, this thing can really let loose.

·  Model is pre-cut and each joint is drilled for super strong connection.

·  Comes with a leather-like sling and some soft modeling clay for safe hurling!

Catapult

The catapult has a long and interesting history. It has been around in many forms, evolving since about 400 BC. This model is based on the medieval styles that were used during the middle ages.

Standing 15 cm tall and 12 cm wide, this siege engine can shoot a plasticine ball over 15 feet!

Adjustable pads on the crossbar allow you to change the trajectory angle. The rope, strung through the middle gives great power to the swing arm!

·  All pieces are pre-cut and drilled so the model is incredibly strong!

·  All you need is glue and scissors.

·  Can be made in about an hour.

·  Great for beginner siege builders!

Great for STEM programs!

Siege Tower

The Siege Tower was use by invading armies to breach the walls of the castle they were attacking. They varied in size and construction,(some up to 135 feet tall!) but the one we have here is typical of the styles used from about 900 BC to the medieval times as attackers tried to get over the walls of a castle.

This incredibly sturdy tabletop model will give hours (years!) of reliable sieging around the house and back yard. Like all of our kits, this one is pegged for great strength and authenticity and will give you that cool siege feeling with the firing catapult on the top.

·  Each piece is pre-cut and pre-drilled for ease of assembly and strength.

·  An easy to raise and lower drawbridge, and a fully working catapult in the top.

Trojan Horse

Ancient Greek legends have many references to the Trojan Horse – a huge wooden horse that was left in Troy – with warriors inside.

When it was brought into the walled city, the warriors came out (late at night when everyone was asleep)and took over and opened the doors to the entrances – allowing the the Greek warriors hiding in the area (outside the walls) to overrun the city.
