well, if you use water instead of milk, it will no longer be milk. it will be colour changing water.
=yes it will help you live longer=
yes milk will help flowers live longer this is because milk has calcium and calcium will make the flower stronger which will make the flowers last longer. ----------------------------------------------------------------------------------------------------- Actually, i don't think it does. My science fair question is very similar to this question (which liquid helps flowers lives longer) and the flower in milk didn't grow and it was never in full bloom. The milk didn't help the flower at all. +) This answer is based on the result that i got from my science fair experience.
I think the milk will take longer as it has some fats in it.
fresh water
Water with sugar mixed in.
yes
regular water (its easy to figure out
Using sugar water is the best method for making flowers last longer. The sugar provides nutrients for the flowers to feed off of, helping them stay fresh and vibrant for a longer period of time. Milk can actually promote bacterial growth and hasten wilting.

water.
Milk powder has less water content than liquid milk, which reduces the growth of bacteria and other microorganisms that cause spoilage. Additionally, the low moisture content in milk powder creates an environment where enzymes that degrade milk components have limited activity, leading to a longer shelf life compared to liquid milk.
