Dropper is a block that drops random items from its inventory as an entity each time it’s powered.
To make a Dropper, you just need Red stone and Cobblestones. Please follow the following steps to make a Dropper.
In order to make Dropper, you will have to find the redstone block. Go to the mining area down stairs and get at least one red stone block.
The next required item that you need to get is cobblestone. You have to find and get at least seven cobble stones.
After collecting required items you need to use the crafting table to craft a dropper. Go towards the crafting table and open up 3*3 crafting grid to add seven cobblestones and one red stone as shown in the image below. You will get a dropper in the right-side box of the crafting table. Add this item in your ready to use stock.
