I want to play a practical joke on my brother in order to scare him. What can I do?

You could put on some scary music, creak the doors and windows to make it sound like there's someone inside the house, set up a few strobe lights, and hide around the corner when he enters the room. You could also use some special effects make-up to look like a monster or use some fake props like chains and blood to add to the illusion.
