USDFEVER is a high impact telekinesis effect. It will allow you to alter the temperature marked on any analog (non - digtal) thermometer, it is totally impromptu and you can perform it either with Mercury or Mercury-Free thermometers.
Although in the demo I perform it altering the temperature while the spectator is holding the thermometer in their hands; this can be performed by leaving the thermometer on a table you concentrate on it, and then have a spectator check it.
The posibilities are endless.
FEVER works only with analog thermometers.
