You know, even travel sizes of toiletries can be way more than you need of any one item.
I repackage almost all creams and liquids in eye drop containers.
Just monkey with the top and the whole thing will just pull away from the bottle.
Rinse the bottle well, fill the bottle with a bit of shampoo, sunscreen, hand sanitizer, or whatever , and pop the lid back into place. Hole in the top too small? A hot needle will enlarge it.

An aluminium spoon can be made into a spork with a hack saw, small metal file, and a bit of wet/dry sandpaper.

You can make a pop can alcohol stove for about the price of the soda cans. These work really well and are very light weight.

I often cook in an enameled aluminium camp cup (Wal-mart about 3 dollars).
my alcohol stove fits inside. So does my spork. (I shortened the handle).
