This is my newest project and group of inventions-its a series called SpyDrinkz! These inconspicuous fast food cups can let you secretly call or text people in almost any situation! Also including a covert charger-cupholder, these cups come in all shapes and sizes, including a coffee cup, a soft drink cup, and a water bottle! I will post these cups as separate Instructibles, so subscribe now! Thanks for viewing!
