You have probably seen balloon arches before, and even rainbow cake ideas…but have you ever combined the two into one adorable cake topper?  It is such a fun little DIY, and only requires five supplies, including the cake!  You know what Julia Child says.. ”a party without cake is just a meeting.”  Well, a cake without a cake topper is like a unicorn without a horn!  We can’t have that.

How-To

DIY Rainbow Balloon Cake Topper

Step 1
Using a balloon pump, blow up 4 balloons of each color.  They should be about the size of a small kiwi. It’s easiest to start large and let air out to get them down to the right size.  The balloon above is pictured with an egg, for size reference.

Step 2
Cut a 30-inch piece of wire, and tie a pink balloon around it, leaving at least 6 inches of space between the balloon and the end of the wire.

Tie a second pink balloon around the wire, and slide it so that the two balloons are close together, and touching.

Continue tying balloons around the wire, until there are four pink balloons all squished together.

Step 3
Now begin tying on four orange balloons, and slide them down to touch the row of pink.  Squish them all together as much as possible so that the wire and balloon ends are not showing through.

Step 4
Repeat this process with four yellow, then green, blue and purple balloons.

Hold the wire on each side at the ends of the balloons, and pull the ends together to form an arch.

Step 6
Estimate the height of your cake, and using scissors, cut the wire down on each side, leaving at least two inches of wire to stick through the top of the cake.  Use soap and water to wash the two wire ends and any balloons that may touch the cake.  Don’t forget to rinse and dry!
