DIY Rainbow Ice Cubes

Who wouldn’t love to sip on a rainbow? I like making these easy rainbow ice cubes for my kids on St. Patrick’s Day, or I’ll use this DIY as an excuse to brighten a boring day. I’ve added these to a punch bowl at a birthday party, too—it makes a fun, colourful impact.

Step 3: Pour into ice trays. If you don’t want to use a whole tray of one colour, just split the colours up. You can even do three colours per tray, making sure not to intermix.
