I know what you are thinking. Many people complain about the different positions of the bulbs. So
when the light changes, there will be a significant position shift, right? But what I want to say
is, come on! We are all professional magicians. Even if you are an amateur, you know how to deal
with it. 1: If the light outside is too dark, you can let the audience close to the pattern to
shine, and there will be no obvious change. At the same time, you can shake their arms. 2: If the
light is very bright, for example, if you perform in the daytime, it is not a problem at all! I have
tried many times. As long as you ask them to hold the flashlight away, about 15-20cm, you can't see
any light changes at all. What I want to say is that this is the only place to practice this magic,
and the rest is fully automatic!
