French bottle water company Vittel is getting people to drink more water... They've come up with an ingenious little way to remind you to drink the recommended eight glasses a day. Special bottles are fitted with a twistable cap and a little red flag pops up every hour to remind you to drink more water! After you drink, you twist the cap closed which sets off a timer that causes the flag to pop up again in 60 minutes. Check it out! ...and drink up!
