Band-Aids/Neosporin

If you're using a combination of band-aids (adhesive strips) and neosporin (antibacterial creme) to heal a wound, apply the creme to the cotton of the band-aid first. If you smear the creme on the wound first you'll likely spread it where the adhesive part of the band-aid is supposed to go, preventing it from sticking. Applying creme to the band-aid's cotton prevents this.
