Hello! I wanted to make a start at cosplay and create some horns to wear on a headbandI wanted to make ram horns, and they'd be really heavy with the air dry clay I haveI don't mind them being heavy, except they may fall off of the headbandI've never worked with polymer clay, so I'd rather work with air dry clay, but if it's much lighter then I would love to use itI'm not sure where to get polymer clay as well, so you may answer that too!
I sincerely apologize, because this is my math, but I very clearly did something very wrongSoI'll post this as an example of what (apparently) not to do(A) The speed of sound in aluminum is 5,000 m/s - 5,200 m/s depending on where you lookI'll just use the middle 5,100 m/s (so for your exact value, you'll have to find the speed that you're supposed to usebut these are close)L c / f L wavelength c speed of sound f frequency L unknown c 5,100 m/s f 2.0 MHz - unit is Hz, so 2,000,000 Hz L (5,100 m/s) / (2,000,000) Hz L 0.00255 m or 0.255 cm [ 2,550,000 nanometers (nm) ] (B) EM in a vacuum? f c / L c 299,792,458 m/s (definition speed of light) L 0.00255 m f (299,792,458 m/s) / (0.00255 m) f 117,565,669,804 s
Polymer clay will be much lighter - especially since you ought to make something the size of horns hollow around a heavy duty aluminum foil core so it is has uniform thickness walls for proper baking (actually air dry should be hollow also, harder to dry) and to save moneyBuy the larger block of Sculpey, etc., to save money although you might want to buy smaller blocks for a lower initial investmentAnd with polymer clay you can glue a much more reliable mount inside to attach.
