THIS was  a good experience  thank you for sharing with us.

I use. 3 inches of water , which I replace DAILY ,and , I cut the bottoms of each flower stem DAILY ,,, I Always use a 💚Vase ,as Stems seem to disappear ,,, I Can keep my flowers 3 weeks ,I FIND CARNATIONS LAST THE LONGESSSSSST

This was a very fun experiment to watch. Thank you!!! 🌹🌹🌹🌹🌹

I loved this experiment. Thank you 👍😊

How fun was this!  Loved it!

Pretty neat experiment! I’d have never thought to try most of those lol

Thank   for  doing  this  experiment.

That was GREAT! Thanks Gooch! Wow i hadnt heard of a lot of those.The battery blew me away the most!
I think these additional ideas people gave should be test #2 & maybe cut to the top 2 or 4 of this competition to compare. I also have heard of sugar (a lot) cold water, put in fridge every night, but who's got room? And cut stem every day, diagonally & fresh reg tap water daily. I've never heard of silver & coins arent silver anymore, so??  If u used a AAA, maybe on round #2 use AA OR 9Volt? Ask followers for ideas on a round #2 that u will do in a month or 2. Anticipation 🎵🎶🎶🎵 gooch is making me wait. 😊 👍👍👍👍👍

Good job, my question was answered and I'll use the flower food packets from now on.

I always trim the rose stem end under water, in a sink for example, then place the rose in a water filled vase. This prevents an air bubble that could  cause the flower head to droop.

Cut bottom of rose stem on an  angle. If you cut it straight across it can rest flat against the vase bottom which can prevent water from traveling up the stem

This was so much fun to watch!!

Copper pennies definitely work well to keep tulips from drooping.

Some of the roses could have drooped because of air bubbles when the stem ends were trimmed.

I used bleach and pennies. Awesome experiment

And I don’t add flower food , unless I have some , and if I do I sprinkle in just a tinny amt , like 1/4 tsp OR LESS

Cut stems under water for Rose better drinking and hydration. Add ice to clean water.

Purple rose is Loyalty. Is related with Royalty

Putting flowers in fridge nightly keeps the lifespan ..

sugar lots of it …2 weeks they bloom so big !!!!!
