Bubble....piak...piak....bubble!!!

U remember that thing shown in the picture above?

u press it, squeeze it like nobody cares and then PIAK!!! and you continue, repeating the same routine, PAIK!!! I don't know about you all, but there is a weird sense of satisfaction squeezing the bubbles just to get that piak !!! sound, and it seems i never get bored doing it.....Is it just me?? or hahahaha...
