Boost your self-esteem with this high-five machine if nobody wants to do it with you! Patented in 1993, this machine allows you to stimulate the celebratory effect of high-5’ing as a convenient outlet for the release of excitement. According to the patent’s instructions, you will have to affix the high-five machine to the wall or set it on a table, as it improves your hand-and-eye coordination and your mood, by giving the plastic arm a high-five anytime you want to.
