Not likely, unless you try it in a poor or less populated area. It would be incredibly risky to try to stick it in your pocket and go through a metal detector or a millimeter wave scanner, also known as an Advanced Imaging Technology (AIT) machine, and plastic explosives stick out like a sore thumb on even the older x-ray machines, and especially the newer CT machines that modern airports in wealthier and more developed countries use for baggage, and at least in the US, increasingly (smaller versions of) at checkpoints.
