These mix ratios are very important or it wont taste right. 1 Menthos for every Liter of soda. Most everyone can get 2 liter bottles so this is for them.

Fill a highball with Ice, add Vodka of your choice. Tastes best with Diet soda.

Open a new 2 ltr pepsi and drop both Menthos mints in it.

When they disolve, fill glass with soda and enjoy.
