To complete this How-To you will need:

A sturdy table
Coupe (or round) Champagne glasses
Champagne, sparkling wine, or sparkling cider

Step 1: Find a table

Find a sturdy, steady table on which you can build your fountain.

Step 2: Crunch the numbers

Figure out how many glasses you'll need in order to both accommodate your guests and ensure that your tower doesn't tumble. Each square layer must become proportionately smaller than the last, so if your base is five rows of five glasses, the next layer must be four by four, and so on.

Tip: A standard-size Champagne bottle will provide about five glasses of bubbly.

Step 3: Get proper glasses

Get coupe Champagne glasses, which are the old-fashioned round ones.

Tip: Use plastic Champagne glasses if you're nervous about your tower collapsing.

Step 4: Begin construction

Evenly align each glass in the bottom layer so that they touch each other, creating a diamond-shaped space between glasses.

Step 5: Build the stories

Place the next layer of glasses so that the glass stems are centered over the diamond-shaped spaces.

Step 6: Repeat

Repeat until just one glass stands on the top.
