The shot ski is an instant party starter. Something about the combination of skis and synchronized shooting really brings out the camaraderie in people. Learn how to make a shot ski in a single afternoon, and enjoy warm, hazy memories for years to come.

What You’ll Need

• A drill
• Safety glasses and a disposable particulate mask
• A 1-3/8in Forstner drill bit
• Measuring tape
• A permanent marker
• Heavy duty clear silicone adhesive (I use Loctite Stik’N Seal Outdoor)
• Four or more thick polycarbonate or acrylic shot glasses. (This thing is going to be dropped, stepped on, strapped to the roof of your car, and generally abused by drunken idiots, so use plastic over glass.)
• An old wood-core ski. The longer the better, but anything over 190cm should suffice. Avoid skis with metal laminate layers as they are harder to drill, and try to find skis with sidewalls intact. Look for iconic models, neon colors, and crazy graphics.

How To Make It

Step 1: Measure the Base

With your donor ski on the ground, measure the ski from the forward base contact point to the rear base contact point. You don’t want to mount the shot glasses on the tip or tail for a few reasons: One, the glasses need to be in approximately the same upright orientation. Two, the shooters at each end of the ski need to have something to grip. Three, it just looks nice to leave a little space.

Step 2: Mark the Shot Glass Placements

Divide your measurement into four (or more) equal lengths, and mark the center of the ski’s width at each division with a permanent marker. Ideally, you want about 18 inches between the glasses. More is fine, but less will cause crowding.

Step 3: Drill it

Find a ventilated area (preferably outdoors) and wear glasses and a mask of some type. You’ll likely be drilling through fiberglass, which will irritate your lungs if inhaled and can cause injury to the eyes. Using the Forstner bit, drill holes through the topsheet at the marks, just deep enough to expose the wood core. A Forstner bit is like a cross between a hole saw and a spade bit; it cuts a smooth, flat hole, excavating the material from inside the hole as it cuts. 1-3/8in seems to be the right size for all the shot glasses I’ve used, but you may need to take yours to the hardware store with you to be sure.

Step 4: Add the Shot Glasses

Affix the shot glasses to the ski using strong glue. I prefer Loctite Stik’N Seal Outdoor because it dries crystal clear, has a shock-resistant flexible hold, and isn’t affected by cold weather. Don’t over-glue, and don’t use Gorilla Glue—it dries yellow and expands outward as it cures, resulting in a mess.

Step 5: Wait

Wait 24 hours for the glue to fully cure.

Step 6: Party

Buy some booze and host a party, then allow everyone to praise your shot-ski crafting skills. Take care (of your liver), drink responsibly, and have fun out there.
