Half a Glass

Half a Glass

Infinite Impact

Most water served in restaurants is never fully drunk — and gets thrown
away. One small ask can save billions of gallons every year.

The Problem

Billions of gallons

Wasted every year

Walk into any restaurant in America. A full glass of water arrives at your table. Most customers take a sip — and leave the rest. That leftover water gets thrown away millions of times a day.

0 Billions

 gallons of water wasted every year
in restaurants — just from unfinished glasses

Most glasses are never fully drunk

Customers are served a full glass automatically — even when they only want a few sips. The rest is poured down the drain.

Clean drinking water is precious

While restaurants waste water without realizing it, 2.1 billion people worldwide don't have access to safe drinking water at all.

The fix is incredibly
simple

Start with half a glass. Refill when the customer asks. That one small change — multiplied across millions of restaurants — makes an enormous difference.

The Visual

See the difference

One simple change at every table. Multiplied by millions of restaurants. That’s the #HalfGlass movement.

How It Works

Three simple steps

Spreads the incoming water evenly across the full width of the tube so every part of the moss layer gets used. Think of it like a traffic director for water.

1

Visit a Restaurant

Walk into any restaurant near you — a diner, pizza place, café, food court. Any restaurant counts. Ask to speak with the manager.

2

Make the Ask

Explain that Save Drop is a water conservation initiative. Ask if they'd be willing to serve half a glass of water first and refill on request.

3

Post & Inspire

Take a photo — with the manager, the half glass, or both. Post on social media with #ServeHalfGlass and #TakeHalfGlass and tag @savedrop2024.

Two Hashtags

One Movement

One tag for restaurants. One tag for customers. Together they cover both sides of the change we need.

For restaurants — their pledge to serve less, waste less

For customers — their choice to ask for less

Anyone anywhere can participate. Just ask for half a glass at your next meal.

How It Works

Your 1-Minute Script

"Hi! Can I ask you a quick question?"

— wait for yes —

"Did you know that most customers never finish their full glass of water — and all that leftover water just gets thrown away? It actually adds up to billions of gallons wasted every year across America."

— pause — let that sink in —

"My name is __. I'm a member of Save Drop — a youth water conservation initiative founded by an 11-year-old that has reached over one million people worldwide. My ask is simple — would you be willing to serve just half a glass of water first, and then refill if the customer asks?"

— smile and wait —

"If you say yes, I'd love to take a quick photo to share on social media with #ServeHalfGlass and #TakeHalfGlass — to inspire other restaurants to do the same. Either way — thank you so much for listening. Every drop matters!"

— wait for yes —

Stand tall. Speak slowly. Make eye contact. Smile! Confidence is

Smile! Confidence is contagious.

If they say no — walk out proud. You tried!
