How to Make a Smoke Bomb With Ping Pong Balls

How to Make a Smoke Bomb With Ping Pong Balls Its easy to make a smoke bomb! You dont even need any fancy chemicals, like potassium nitrate or ammonium nitrate. Heres how to use a ping pong ball to make a smoke bomb.   Ping Pong Smoke Bomb Materials Each ping pong ball makes one smoke bomb. You will need: ping pong ballaluminum foilpencillighter Assemble the Smoke Bomb Start by poking a hole in one side of a ping pong ball.Keep working at the hole until its large enough to insert the pencil into it. Put the pencil in the ping pong ball.Wrap aluminum foil around the ball and the pencil. Dont completely cover the pencil. What youre doing is making a nozzle for the smoke, so work an inch or two up the pencil.Remove the pencil. The ball plus foil is your finished smoke bomb!Take the smoke bomb outside and use a lighter flame to heat the foil on the bottom of the ping pong ball until smoke starts to come out of the nozzle. Set the smoke bomb on the ground and enjoy the show! How a Ping Pong Smoke Bomb Works You may not have realized it, but ping pong balls are made of nitrocellulose the same chemical used to make flash paper and the one that causes old movie reels to burst into flame. Ping pong balls are stable, though, and wont burn unless a heat source is applied. You may wish to burn a ping pong ball to see whats happening inside the smoke bomb: How To Burn a Ping Pong Ball (safely) If you burn a ping pong ball in the open, it produces some smoke, but not as much as youll get if you cover the ball to control the amount of oxygen and thus the rate of combustion. Making a spout or nozzle to control the incoming air and outgoing smoke also improves the smoke bomb.

Suppletion Definition and Examples in English Grammar

Suppletion Definition and Examples in English Grammar In morphology, suppletion is the use of two or more phonetically distinct roots for different forms of the same word, such as the adjective bad and its suppletive comparative form worse. Adjective: suppletive. According to  Peter O. Mà ¼ller et al., the term strong  suppletion is  used where the allomorphs are highly dissimilar and/or have different etymological origins, as in the adjective forms good and best. We speak of weak suppletion if some similarity is discernible, as in the words five and fifth (Word-Formation: An International Handbook of the Languages of Europe, 2015). Examples and Observations Bad - worse is a case of suppletion. Worse is clearly semantically related to bad in exactly the same way as, for example, larger is related to large, but there is no morphological relationship between the two words, i.e. there is no phonetic similarity between them.(J.R. Hurford et al., Semantics: A Coursebook, 2nd ed. Cambridge University Press, 2007)Suppletion is said to take place when the syntax requires a form of a lexeme that is not morphologically predictable. In English, the paradigm for the verb be is characterized by suppletion. Am, are, is, was, were, and be have completely different phonological shapes, and they are not predictable on the basis of the paradigms of other English verbs. We also find suppletion with pronouns. Compare I and me or she and her. Suppletion is most likely to be found in the paradigms of high-frequency words. . ..(Mark Aronoff and Kirsten Fudeman, What Is Morphology? 2nd ed. Wiley-Blackwell, 2011) Good, Better, Best The forms good, better and best, which belong to the adjective good . . . show suppletion since the relationship between the morphs representing the root morpheme is phonologically arbitrary. It would plainly make no sense to claim that there is a single underlying representation in the dictionary from which go and went or good and better are derived. The best we can do is to content ourselves with listing these allomorphs together under the same entry in the dictionary. (Francis Katamba, English Words, 2nd ed. Routledge, 2005) Origins of the Forms of Be and Go The Old English verb for be, like its Modern English counterpart, combined forms of what were originally four different verbs (seen in the present-day forms be, am, are, was). Paradigms that thus combine historically unrelated forms are called suppletive.Another suppletive verb is gan go, whose preterit eode was doubtless from the same Indo-European root as the Latin verb eo go. Modern English has lost the eode preterit but has found a new suppletive form for go in went, the irregular preterit of wend (compare send-sent). (John Algeo and Thomas Pyles, The Origins and Development of the English Language, 5th ed. Thomson Wadsworth, 2005). Origin of the Term  Suppletion in Linguistics The term suppletion gradually makes its way into grammatical descriptions and other linguistic works in the late 19th century (Osthoff 1899; Thomas 1899:79). In grammars it was probably triggered by the preceding notion of a defective paradigm; e.g. if a verb lacks a form in a certain category, it is supplied by some other verb.In linguistic theory of the 20th century, suppletion came to be fully established as a concept with the advent of structuralism, where the relation between form and meaning as well as the understanding of paradigmatic relationships became very important for a synchronic language description.
