This occurs because the velocity of the wave is different in each medium.<\/p>\n<p>When an object is immersed in water, the light entering the object passes through the air-gel interface and is refracted due to the difference in the refractive indices of the air and the object. Then, when light passes through the gel-water interface, it is refracted again due to the difference in refractive indices.<\/p>\n<p>However, since the gel ball has the same refractive index as water, there is no difference in the speed of light in the gel and in the water, so there is no refraction when light passes through the gel-water interface. In this case, light enters the gel ball and will leave it without changing its direction of propagation, so the gel ball would appear \"invisible\" from the outside. In this way, only the decorative elements you have placed are visible.<\/p>\n<h2>SEE OTHER ACTIVITIES<\/h2>\n<p>You can see other activities and kits here: <a href=\"https:\/\/www.alquera.com\/en\/experimentos-de-ciencias\/\">Activity kits<\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>Clear gel balls are an excellent choice for making floating candles as they have the same refractive index as water, which means they do not refract light and therefore do not distort the colour of the light. In addition, gel is a safe and durable material, so you can enjoy your floating candles for a long time.
