I just poured jet fuel on my brain an besides the awful smell it does not seem to have a large effect. Maybe it takes a few days, so I will leave it on for a while.

In case you wondered how I got access to my brain, this old tool proved helpful: https://www.catawiki.de/l/14535665-trephine-skull-drill

And yes, this was a joke and I do not recommend trying this at home. Ask your trusted surgeon for advice.
