Feargus O’Sullivan reviewed Paris’ sparkling water fountains:

• Paris currently has a network of 8 sparkling water fountains – and it is looking to expand.
• Officials say that they promote hydration – more people are willing to replenish themselves if the water sparkles.
• The fountains themselves don’t look that glamorous; the one O’Sullivan reviewed was covered in graffiti and slime.
• The water, though, was delicious, and may well encourage passer bys to take a gulp.
