World's Largest Spirograph

I am set on making the World's Largest Spirograph.  I wanted a huge one, and could not find paper big enough for a four foot one I made (pictured), so I adapted it for working on pavement, with sidewalk chalk.  

I really loved making improvements every step of the way- from a chalk dispersal unit to custom shocks for uneven and bumpy pavement.

I had a lot of fun, and wanted to share it with others.  We have whats called an Art Hop here every year in Burlington, Vermont.  A local buisiness was doing chalk and a STEAM expereince anyway, and they loved the idea I was going for...World's Largest Spirograph.  20 feet!  They are giving me the whole parking lot to use, and its during a busy night that is kid-centric.

So, while the build will be funded to make it by Sept 8th, fast tracking any Guiniess Book of World Records costs $1000.  5 day turnaround acceptance, rules and such.  Otherwise it takes up to 15 weeks! So that is where the money would go, making sure  all rules and regulations for declaring it the World's Largest Spirograph in time for the Art Hop.  

It will really benefit the maker community to have that kind of validation, and show kids that big dreams can come true.  I am very grateful already for the support the community has shown behind this.  

I am making it regardless, it would just nice to be official on time.  I cannot wait to start!
