Things that were suppose to blow but only ended up sucking

Once again I find myself failing miserably at building wind instruments. Here is a whole rack of bamboo flutes that do not make a sound at all. I will admit that I know nothing when it comes to playing wind instruments, but the lady here has a Clarinet which makes a sound every time I put it to my mouth, grant it that sound is not what one would call pleasing to the ear, but it is a sound. I think it has something to do with my blow hole and I’ll leave it at that.
