Mar 29, 2013 US Pineapple grenade project poll We need your help! How much would you pay for a display quality reproduction WWII US pineapple grenade that actually "worked"? You would pull the pin, pop the spoon and the grenade would make a loud bang sound (about as loud as a blank rifle round.) If it was easy to use, safe, and cost about $2 to refill? We need to know because this is a huge project that will cost a lot to set up and we have to know how much we will have to sell them for in the end. Ask your friends, contact us, please tell us what you think.
