For my final trigonometry project I have to build a car out a vegetables. I want it to look like Cinderella's carriage. I know how I want to build the body, but with the wheels, I'm having a problem. I want to use radishes as wheels, but that can change if it has to. the radishes will not stay on the toothpicks. (I have to use all natural materials that aren't processed. Yes, I know that toothpicks technically are, but I'm only going with what my teacher has said.) Carrots will even slide off. Help?!

Water and flour makes a passable glue - it's what people used to hang wallpaper for many years. I guess the milling of wheat/corn would count as processing though. I would use knobbly twigs as the axles and hope that I could use the terminal bud as an end to stop the wheel coming off.

 

and did you say trigonometry?

Maybe , you could use bamboo in your design .

There are any number of round vegetables that could be sliced to make any width wheel.

yes, i plan on using radishes. however, they slide right off. i need to find a way to keep the wheels on, like an axel or something. (I can use wood and bamboo)

If you have the time and effort -

- use bamboo and just slowly whittle a hole in the bamboo close to end (ie outside where wheel goes)

- I would cut a notch in each side and then poke/drill through

- cut a very slender needle of bamboo

- put wheel on

- put needle of bamboo through hole to stop wheel coming off

- if you want wheels to turn without fouling bamboo needle use thin and small radius piece of radish as washer between wheel and needle

 

and seriously trigonometry?

I would try to think of ways to attach coconuts as spherical wheels with drilled holes in either side , to bamboo ( inner axle and outer bearings , cooking oil for lubricant ) and attach this to a strong bamboo frame and attach a pumpkin to that . The arty , decorative part is left to the imagination , I might have gone somewhere on the structural part though .

 

I hope I helped .

yes, it is for trig, but there's a math and a research portion to it. most people have been through physics already, though.

If you need a natural glue, milk+vinegar (and then baking soda to the watery part without the curdle) makes a great and quite powerful glue. The curdled part, by the way, can solidify after 48 hours to something quite strong and plastic-like.
