Just a Splash of Color
One thought that I had was to find a way to color the water for a floating candle centerpiece. It would be simple to add some food coloring to the water and call it a day but sometimes it just makes the water look dark instead of colorful. So my idea is to use the light up ice cubes that are used to make drinks fun for the centerpiece water. They not only add color but they are water proof and will light up the centerpieces as well.
