You might want to add that people should not DRINK those drinks!
Dry ice is not just very cool ice, its actually a special mix of chemicals, and therefore just touching it with your hands without wearing special gloves would harm you A LOT. So drinking a drink with dry ice in it would probably kill you, so please edit your guide a bit
Anyways, yeah dry ice is awesome, it can cool your PC, it can look cool when tossed into hot water (smoke!) and it can be put into bottles with water to make dry ice bombs (google.com) but yeah.. edit your guide pls
