When Hup Seng meets Ritz

I can't recall when was the last time my mother scolded me for playing with my food. Guess old habits die hard, I started stacking my Hup Seng biscuit and Ritz with peanut butter to form some sort of spring suspension.

I can use this for my math class, asking my students to calculate the height of the Hup Seng biscuit using trigonometry. -.-''
