How many new experiments have you seen in this video
Hello friends I congratulate you on the New Academic Year I suggest you take part in a small quiz of my experiments. As a task, write in the comments the answer to the question How many new experiments did you see in this video. It will be wonderful. I will also be able to make other interesting videos for you. I have also prepared two books for beginners for this academic year. Take a look at the products that are sold in the store under this video. I also invite you to follow my Telegram channel. Sincerely, Yuri Kovalenok
