One of the Fortnite Chapter 3 Season 2 week 2 challenges is to destroy structures with propane tanks. This is part of the TNTina trial, and there's a spot in the game that's perfect for this challenge.
The Rig, one of the new points of interest added to the game in Season 2, is absolutely full of propane tanks. Head straight from the Battle Bus and land on the bridge. It's a good idea to jump into the phone booth to disguise yourself as an enemy, allowing you to easily gather propane tanks.
Propane tanks are bright red, with yellow writing on the side. You should know that a single propane tank does not do enough damage to destroy a structure, and you have to destroy them for this challenge, damaging them is not enough.
You'll need to stack three propane tanks in a small area to do enough damage to destroy a structure. So take three tanks and take them somewhere that has lots of structures close to each other. The 2 spherical tanks on the main deck are a very good place to put them. Then shoot one of them and watch them all explode, destroying the structures around them.
You can find propane tanks on other parts of the map, but not in the quantities that they can be found on the platform. If you'd rather just finish this somewhere else, use your harvesting tool to lower the health of the structures you want to destroy, then use the propane tank to finish them off.
When you've destroyed 10 structures with propane tanks, the challenge will be complete, bringing you one step closer to TNTina's Shadow or Ghost styles.
