How can I destroy a block from afar?

I've been playing on the PPCG Minecraft server for a little while, and I've managed to build a fairly decent tower, but someone has decided to do this, right next to the top:
While I could build out and get it, I don't have a silk touch pickaxe, which means I'd have to make more glass, and I'd lose some resources due to the height as well.
Is there any way that I can destroy this block from afar? Do note, I don't have command privileges.
Best Answer
If you want to destroy a block from a distance, a TNT cannon could be used. This would use more resources than just building a bridge to get there as every TNT takes 4 sand and you would need about 6 TNT per shot. Right there that would be 24 glass without counting the other materials needed (gunpowder, redstone, etc.)

How do you break blocks from far away in Minecraft?
Initially only a few block types can be feasibly broken using only your hand, including dirt/grass, sand, wood and leaves, so try left-clicking and holding and see if you can break these types of blocks. If nothing is happening when you left click, then your mouse button might not be properly mapped.How To Execute The Fill/Remove Command in Minecraft Bedrock
