![My daughters bought me a rose for Valentine's day. We put blue food coloring in the water as a science experiment. [3072x4096 - 2.31MB]](https://pic8.co/sh/He6qJk.jpg){kind=link}
A cool experiment showing transpiration.
On top of adding 20 odd drops of food colouring to the water, you can also add saccharides or other simple sugars to increase the longevity of the flower in the vase.
Alternatively use hydrangeas and change them from pink to blue by adjusting potential hydrogen (pH) lower with acids like cooking vinegar or copper coins in a vase.
An interesting application of science to get children captivated in the natural world.
u/ThisIsMyRealName, nice apolitical post for a change on poal.co

Saccharides..that’s a word I haven’t heard in a long time.
Thank you! I'm trying to ween myself off politics and get back to my roots (no pun intended). I miss the early days of Voat back before everyone was so pissed off.
