Burning calculator destruction

Video description:

A vintage beige calculator is being destroyed by intense flames that appear to be coming from a heated metal ball or object placed on top of it. The flames grow progressively larger throughout the sequence, completely engulfing the calculator's keypad and display area. The calculator sits on what appears to be a concrete surface, and the fire creates bright yellow and orange flames with white-hot centers. The destruction appears complete as the flames consume the plastic housing and internal components of the calculator.
