This is how i found you can make upside down pessure plates!
I haven't used it for anything yet but it looks cool.
P.S. i have a prototype chest as well!



Here is the command: /summon MinecartRideable ~ ~1 ~ {CustomDisplayTile:1,DisplayTile:1,DisplayOffset:-25}
you can enter into a command block (/give [PlayerName] Minecraft:Command_Block) or in the chat commands

That's all for now. Hope you like it!

Thank you for getting me on the hot reel!
