The popcorn butter oil does what you expect, but if you've ever wondered why your popcorn has never tasted like movie theater popcorn, it's because you didn't have flavacol. Flavacol is pretty much popcorn salt, the stuff you may or may not have seen employees grab a cup of and sprinkle over freshly made popcorn after it's popped in their machine. You need to be VERY mindful with how much you add though, it's extremely fine and you really don't need much. I'm a sodium whore and yet I do no more than a teaspoon. The amount of flavacol in that carton will last you an eternity.
Some people also use coconut oil with this combo and that's apparently even better, but to me popcorn oil + flavacol is all I need. I've eaten more popcorn in the past 2 months than I have in all of 2019 and 2020 combined.
you might want to suggest your brother to read THIS book, it talks about how Americans are exposed to so much fantasy and conspiracy that they think everything is a conspiracy, something along those lines, it ll clear his head
Here is a great pdf debunking it. https://dochub.com/wishlistwanderer/5lae27DR5EvZo83RmqjZv1/plandemicdebunked-pdf?dt=mfVUAguoK9yVH9-FzkaN&pg=9
Try surgical tape either across your nose (sometimes helps make a better seal) or on top of it (to cover the crack around your nose).
Edit: You can also buy nose wires on Amazon (example here)
