1 1⁄2 Liter (2 Bottles, In Addition 1/4 Myers Dark Rum May Be Used For Flavor)
1⁄2 Pint (Any Peach Flavored Liqueur Will Do)
1 Pound, dissolved as syrup
Mix together as the base ahead of time.
Put cake of ice into punch bowl, add 1 bottle of mix plus 2 bottles of sparkling water (Canada Dry).

Replenish punch bowl often as necessary.
If you still want to spike it but wish to preserve the original flavor, use high proof (100 or over) vodka.
