i dont see how the effects would be any stronger than the real deal. you would probably be better using even a pipe. i would never go through all the trouble of doing that. the only time i tried something really funky was making a bowl out of a big red apple way back in the day. it tasted good, but it hit terrible. it definitely wasn't worth the hour and a half or w.e that it took me.
its a novalty/party trick type thing, no real point, just fun to make and use. an hour and half to make a pipe bong seems a little excessive lol all you do is poke a hole in the side and carve out a little bowl ontop, you dont even need tinfoil lol
that doesn't make any sense lol how are you supposed to smoke through it wihtout foil? i got all fancy with it. i carved out the inside of the apple leavin a few small holes. one of which i stuck a straw to inhale from and the other one was for the foil. i cut little slits around the hole to stick the ends of the foil in to hold it in place. it was interesting tho. i have a pic i'd show you but i don't feel like uploading it from my phone haha
lets say you have a Bic pen that has the inner ink tube you can take out. push the entire pen though the side to make the "inhale hole" lol. then carve a small bowl in the top middle of the apple, take the ink tube from the pen and push it down through the bottom of the bowl till it hits the other hole and make sure you can suck through. then take a lighter and seal the bowl with the flame. and there you have it you can also have the "inhale hole" run horizontal through the entire apple so you have a carb at the other end.
