This 3M 391X air release tool is a retractable, very small pointed tip used to puncture a vinyl bubble and release the trapped air.This is a video that Fellers, the world's largest wrap supply company, asked The Wrap Institute to make for their catalog.
These two classes of consonants are the plosives and fricatives. Plosives are the kinds of sounds usually associated with the letters p, t, k; b, d, g, in which air flow from the lungs is interrupted by a complete closure being made in the mouth.
It's made by a quick puff of air being force through the mouth, and the /b/ buh sound can't really be stretched without being distorted. Some other short sound letters include C, D, K, G and a few others. The 3 year old child in the video below demonstrates phonetic reading, and how to make the proper /b/ sound. /b/ denotes the buh sound of letter B; however, it's important to note that you don't actually say buh where the -uh part is not voiced. So you can't really stretch the /b/ sound by saying buhhhhhh.
