8 high-tech Halloween pranks to spook your friends

If you have an excessive budget for your haunted house, then you might consider startling your friends with this unconventional door scare designed by special effects company Hi-Rez Effects.

The idea is that you would set up a video display on a fake steel door, which would occasionally show an evil nurse walking towards the door. The nurse will walk around for a while, but eventually she’ll take interest in the door and the viewer. As she walks up, she grimaces and attempts to stab a nearby door user with a big metal syringe.

The screen syncs up with a mechanical prop that would attempt to “stab” the viewer with a big syringe – don’t be too worried though as the needle is made of vinyl tubing. On the crap-your-pants scale, this could get some big results out of your friends. However, the DVD, video display and mechanical prop cost more than $850 (about £556, AU$1,197) in total. Now that’s a frightening figure.
