Ice Spark is also another cool product that offers a similar solution to the heat in Japan: it sprays a freezing -9 degrees Celsius gel that fizzes on the user’s skin, creating a satisfying bubbly sensation. The crackling sound is particularly pleasing to the ear and the gel dries up after a couple seconds, without leaving a sticky feeling on the skin. The spray can be used for different purposes, such as a citrus smelling deodorant.
