Magic sugar claims to be a device that can melt sugar. Its principle is based on the mysterious scientific theory of "quantum physics". However, this theory has not been recognized by the scientific community, and there is no scientific basis and experimental evidence to support its effectiveness. In addition, there are some problems in the propaganda language and way of magic sugar, such as exaggerated propaganda and false propaganda, such as claiming that sugar molecules can be rearranged, thus changing the taste and nutritional composition of sugar. There is no scientific basis for these propaganda, and it can be concluded that magic candy is a scam.
