This effect is really fun and cool
Imagine we take a small sticky note then we stick it on the back of the cellphone,
Then we can draw, write whatever we want,
After that when we flick our finger suddenly the image or writing changes instantly....
The spectator will definitely be stunned to see this..!!
Then we can peel off the sticky note and give it to the spectator for inspection.
And this is :
No pulls
No magnets
No chemicals
Very visual and practical
Perform anytime & anywhere
