take two bags, one bigger then the other and a piece of tape, put the seeds in one bag- melt it shut. take the other bag and place pepper in it. do this in advance b4 the plane, u can put it in the pocket of a pair of pants in your bag, you can also tape it to ur upper leg, next to ur pocket, u wont lose it and f its getting loose, just make it like ur pickin a wedg and fix it up, works everytime, also depends on what kind of seeds they are, there are so many ways its unbeileveable im sure youll figure it out..
in domestic i just put the bag into shampoo bottle(not clear) in toiletries. works everytime.
