If you are afraid of ingesting anything, drink 2 packs of milk, or/and consume the white of a few eggs.
As Rhodium already indicated, you need some active material which will amalgamate the spilled mercury forming a silvery surface.
If you can get hold of pure Iron dust by filing a piece of iron laying around in your garage, that will also help. Most people have no zinc dust laying around. Any Aluminium dust will also help.
Remember to brush up those amalgamated dusts, do NOT use a vacuum cleaner, or be prepared to throw that one away.
The problem is ofcourse the fact that you have a Hg-salt in alcohol spilled.
I look up the best way to deal with that.
Did you have it on a wooden floor, or concrete, or a tapestry? LT/
