Ever since printables first hit the party scene back in 2009, I have been redecorating water bottles to co-ordinate with the party theme. The idea is simple but really is one of those “attention to detail” things I love doing at every party. You buy individual water bottles for guests and then cut off the label. You then stick on your own custom-made label that co-ordinates with the party theme. You may just use the design or logo of the party or “name” the water to suit the theme. For example: at a Cowboy Party I called it “From the Watering Hole” and at a Woodland Party “Dew Drops”.
But I have to say this one for the Science Party may just be the best one yet: H2O!
