When they mistake the LifeStraw for a bong.
LifeStraw is a portable water purification tool that cleanses surface water and makes it safe for human consumption. It is just 25 cm long and 29 mm in diameter and can be hung around the neck. LifeStraw requires no electrical power or spare parts. It filters up to 700 litres of water and effectively removes most of the micro organisms responsible for causing waterborne diseases. LifeStraw® kills disease causing micro organisms which spread diarrhoea, dysentery, typhoid, and cholera. LifeStraw® filters bacteria such as Shigella, Salmonella, Enterrococus, Staphylococcus Aureus and E .Coli. LifeStraw® contains a specially developed halogen-based resin, an extraordinarily effective material that kills bacteria on contact. Textile pre-filters are used in the LifeStraw® to remove particles up to 15 microns. Active carbon withholds particles such as parasites. Do not taunt LifeStraw
