First of all, I will experiment with the disinfectant that I investigated in the research from last year. The disinfectants are as follows.
I am putting natural water in a graduated cylinder.I haven't used it in the image, but it's very difficult to put it in a PET bottle without using a funnel.
I am putting sugar in a graduated cylinder.Since sugar is packed individually, it is unlikely to slip.
I put bleach in a graduated cylinder of bleach.It was difficult to put it from the dropper little by little.
I put flowers in a graduated cylinder.
For the experiment, we will use a flower called gerbera this time. The reason is that gerbera has more bent stems and withers than other flowers, and it is easier to see how it is withered than other flowers. Also, the reason for changing the color to red shows our enthusiasm.
1 First, cut the copper plate into three squares of about 1 cm and fillet with water. 2 Add 100 ml of water to 21 graduated cylinders from the watering can. 3 Put a copper plate in 7 of them and 10 ml of carbonated water in 7 of them. 4 Add 800 ml of water and 4 ml of bleach to the watering can, and add 100 ml to the remaining graduated cylinder. 5 Put 5 grams of sugar (granulated sugar) in all graduated cylinders. 6 Finally, wait for a few days, check the reduced amount, measure the length of the stem, and then continue at the same rate.
Which fungicide will make the flowers last longer? I made a prediction.
