Strum all the strings open, then lay one finger straight across every string. Open: B. At fret 5: E. At fret 7: F♯. At fret 12: B. Those are the I, IV and V chords of the key, enough for a blues or a folk song.
Open tunings are the classic choice for slide: hold the slide straight over a fret line and every string rings the chord.
Starting from standard tuning: 6th string down 5 semitones to B; 5th string down 3 semitones to F#; 4th string down 3 semitones to B; 3rd string down a half step (1 semitone) to F#; 1st string down a half step (1 semitone) to D#. Use the tuner at the top of this page for each changed string.
From the lowest string to the highest: B1, F#2, B2, F#3, B3, D#4 (B F# B F# B D#).
Reverse the changes: 6th string up 5 semitones to E; 5th string up 3 semitones to A; 4th string up 3 semitones to D; 3rd string up a half step (1 semitone) to G; 1st string up a half step (1 semitone) to E.
Tuning down a lot makes strings slack, which can buzz. If it does, use a heavier string set or play a little lighter.
