Today, me and puzzle1cisuM90 are bringing you the fastest 4x4 trapdoor ever made. Taking only 7 ticks to open, blink and you'll miss it! It's not amazinlgy compact but you can cover the top with blocks to hide it, and it is also only 3 tall, so it can slot into any decently sized ceiling. You should definitely check out puzzle because he does some amazing stuff:
