Details

Can five 16 inch dowels, ten 2 ft long pieces of wood, and 26 rubber bands (total weight of 5 lbs for all parts) be used to build a bridge which spans 5 feet and can carry 60 lbs? You bet! Leonardo da Vinci’s bridge can do it! This kit allows you to build it yourself! Once you’ve caught the principle behind it, who knows what you’ll build!

Leonardo da Vinci invented this bridge between 1485 and 1487 for his patron Cesar Borgia. Cesar was looking for a light and strong bridge that his troops could deploy quickly – one that required no woodworking expertise or knowledge. Da Vinci’s bridge fit the bill perfectly. It has only 2 unique parts and is completely self-supporting.

Unlike this kit, da Vinci’s original design requires no fasteners. Instead, the beams have notches cut in them to suppress lateral forces. For simplicity, this kit does not include notches but uses rubber bands as fasteners. Using rubber bands has the added benefit of allowing us to see how force is transferred in the bridge. The rubber bands stretch as weight is applied, showing how gravitational forces are transformed into lateral forces

Kit includes ten 0.75” x 1.5” x 24” wood beams, five 0.75” x 16” dowels, 34 #64 rubber bands, cardboard storage box and instructions for assembly and experimental activities.

The Eisco Garage Physics line is aimed at students interested in STEM concepts included physics and engineering. Each kit engages learners to discover new ideas about the physical world through assembly and play.

What Educators are Saying About Geyer

Justin has been nothing but helpful and professional in my requests for these Boeing Defense requirements. He has been able to answer my questions and concerns quickly, and helped in securing the order that I may have made with another supplier had be not been the value-add that he is to your company. I hope his merit raise this FY was "exceeds expectations".

..I contacted Geyer via email. I had an email back within minutes!.. A back and forth via email sometimes takes days with other companies and customer service doesn’t happen like this very often. When it does, it’s much appreciated. Brett at Geyer was very polite and accommodating!

John C.

The customer service rep went as far as to reach out to the manufacturer of a product to answer my question, and then provided pictures. She really went above and beyond and answered the question thoroughly and gave me exactly the information I was looking for. This entire process was also extremely fast.

I called to ask how to submit a Tax Exempt Certificate for my library and spoke to a real person, no automation or asking me to press a number. He was friendly, helpful and got our Tax Exempt status established immediately.

...I don't think I've ever experienced that level of customer service before, and taking it into consideration along with the quality of their products, I would absolutely recommend Geyer to fellow teachers.
