lxii - Silica Gel - "Do Not Eat"

semalam along dok tgk mummy chew vitamin C tablet
dia pun sibuk nak jugak 
"along nak ubat sakit.." 
offer dia minum scott emulsion
takmo gak.. dok sebut nak 'ubat sakit' gak
upanya baru mummy tingat dia nak
pil homeopathy yg bg dia mkn before ni..
bekas ubat tu ilang kat mana ntah
sbb diorg asyik dok usung buat main
last2 jumpa bawah katil dalam bilik teh..

adik pun sibuk nak makan gak
padahal before ni dia luah jer pun
pas makan sorg 2 tablet pakat nak lg
pastu pakat main botol ubat tu
botol yg ada ubat mummy tak bukak
bukak yg botol kosong tp ada silica gel bg kat adik
tau2 along dok amek main

ntah camner along tnjuk silica gel packet yg dia dah koyak
pastu tgk muka dia yg lain mcm
pas tertelan benda tu
huhu..
nampak pack yg koyak tu cam kecik jer
hopefully along tertelan 1 @ 2 biji jer
hari ni google info ni
hopefully along takde side effect
huhu..


The contents of a silica packet would make your mouth as dry as a desert.
What you would be consuming is most likely silica gel or some other desiccant -- something that absorbs (collects) and holds water vapor. These little packets are found in all sorts of products to help maintain quality.

Shipping can cause all kinds of atmospheric conditions and changes in temperature. Increased moisture can spoil or permanently damage many products. For example, if a bottle of vitamins contained any moisture vapor and was cooled rapidly, the condensing moisture would ruin the pills. You'll find little silica gel packets in anything that would be affected by excess moisture or condensation.
Silica gel can adsorb about 40 percent of its weight in moisture and can take the relative humidity in a closed container down to about 40 percent. Once the gel is saturated, you can get rid of the moisture and reuse silica gel by heating it above 300 degrees Fahrenheit (150 degrees Celsius).
Silica gel is nearly harmless, and that's why you find it in food products. Silica, which is actually silicon dioxide (SiO2), is the same material found in quartz. The gel form contains millions of tiny pores that can adsorb and hold moisture -- it's essentially porous sand.
While the contents of a silica gel packet are basically harmless, it would be a rather unpleasant experience to attempt to consume the silica crystals. The sole job of these tiny desiccants is to adsorb moisture. If you emptied a packet of the stuff into your mouth, the moisture would be whisked away from the sides and roof of your mouth, your gums and tongue -- giving an entirely new and all-too-accurate meaning of the phrase "dry mouth." If silica gel did happen to make it past your mouth -- which is unlikely because you would probably be making every effort to spit it out -- you might suffer a few irritating side effects, such as:
    * Dry eyes
    * An irritated, dry feeling in your throat
    * Aggravated, dry mucous membranes and nasal cavity
    * An upset stomach or stomach discomfort
So just how many silica packets would it take to adsorb all the water from someone's body? Let's use a 210-pound man as an example. We know that 70 percent of a human body is made up of water - 70 percent of 210 pounds is 147 pounds of water. We also know that silica gel can adsorb about 40percent of its weight in moisture. So 10 pounds of silica gel are needed to adsorb 4 pounds of water.
It turns out that it would take 367.5 pounds of silica gel to adsorb 147 pounds of water. Since a single packet of silica gel weighs 0.1 ounces, that means a 210-pound man would have to consume 58,800 packets of silica gel.
