depends on the form, well i have only seen acid in blotter/tabs around here. but it can be in pill form or just in liquid you can drop on sugarcubes, ect.
you suck on the tab, getting all of the cid outta it and can swallow if you want to.
but mrojas i reaaally dont recommed doing acid as your first hallucinagen. shrooms are less intense (from what iv heard) so maybe start with those or salvia. although salvia cant really be compared, and im guessing shrooms on some levels.
edit- oh nvm just reread and saw you were only wondering what it looks like, w/e im still keepin the rest up
