I use this when I teach the Scientific Method. We talk about observation and show them this effect.
You have to be careful with the distance you do this with your audience. That is why it is a 4 but
love the effect
what distances is it prime at i own it and looked it over but after reading these reviews Im wondering if i should evern bother with the print costs, i planned on using this in the street both day and night.
