in the UK they are called "Catapults". so says my British freind.
i've been playing around with slingshots for about a month. i didn't grow up with slingshots cause i had guns at an early age. i had BB, and Pellet guns, to start with, and graduated to a bolt action .22 Cooey at about 10 years old. days spent stalking gophers are fond memories!

yesterday morning i went out to the shop and built a three cavity mold for .375 round ball ammo. this morning i poured a couple hundred lead balls. it took less than a dozen shots to take that beer can apart.
the wire-frame Flip with the blue bands is DIY.
i used 1/4" aluminum stock and bent it in a bench vise. the band set is a replacement set made by Crossman. weight is 1.5 ounces.
