For my project, the researcher did some experimentation before proceed with real one. One of that is testing the led with the right battery. With 9 Volt Battery the LED completely burned out because of overcharged. So the researcher tried with 1.5 Volt. But the light was still dim. 3 Volt battery was worked excellently with LED.

For the pop up poster, it was made in a small paper first to see how it is going to look.
