Make a Cold Pack from Hot Ice

There are a few different ways you can make your own chemical cold pack. You could mix citric acid and sodium bicarbonate or you could mix barium hydroxide with an ammonium salt. If you have baking soda and vinegar, you can prepare your own hot ice or sodium acetate and then use the hot ice to make a cold pack. This method is pretty neat because crystallizing the sodium acetate generates a noticeable amount of heat. Dissolving the hot ice then absorbs the heat, so you can use the same chemical to make a hot pack and then a cold pack. Heres all you need to do: Hot Ice Cold Pack plastic bag with zipperhot icewater The hot ice needs to be sodium acetate trihydrate, which is the hydrated hot ice that you get right after you crystallize it. If you only have dry sodium acetate you need to dissolve it in the minimum amount of water and crystallize it. Now, just place your hot ice in the baggie and add a small volume of water. There you go... an instant cold pack! The reaction wont get super-cold (only about 9-10Â °C), but its enough to be noticeable, plus the chemicals are re-useable.

We re Still Divided By Race By Carly Morris - 1132 Words

In the past, humanity faced diverse hardships that were presented differently each time. These hardships include gender, ethnicity, culture, religion, the list could go on for a massive amount of time. And each time, communities have tried to fight back, and with the right kind of effort, won the rights to what they were fighting for. Just like how African Americans, Asian, Latinos, and Whites fought each other for the right of being integrated. However, in today’s society, the public has forgotten their fight for integration, and has segregated themselves through choice. Many folks agree with this notion, making various videos, articles, and maps to educate the world. The video â€Å"Racial Segregation in American Schools†, by Carly Morris, claims how segregation has come back in the deep southern parts of America. Also, a map titled â€Å"Racial Segregation in American Cities† continues to show us the ongoing theme of the separation of people. Similarly, the a rticle â€Å"We’re Still Divided by Race†, by various authors, talks about how segregation is still around, whether by design or by choice. Through numerous appeals and strategies, they all convey the shared argument that personal preferences lead to the segregation of mankind. The transcript of â€Å"Racial Segregation in American Schools† is one of the many things that continue to convey the theme through Pathos.

Position Paper to Legalize Alcohol Essay Example For Students

Position Paper to Legalize Alcohol Essay Segregation of a Different Sortâ€Å"If we adults between 18 and 21 can still be trusted enough to fight in wars, if we can be trusted enough to vote for our leaders, if we can be trusted enough to have sex, then why the hell can’t we be trusted with a glass of wine?† Shamed DoganBy law, anyone 18 years and older will be tried as an adult in court, is allowed to vote, and is required to pay taxes. On one’s 18th birthday the law no longer views him as a child yet he is restricted from many places of social activity. Bars and many dance clubs are strictly for those 21 and over due to the legal drinking age in America, so many legal adults are not permitted entry. Clearly a discrepancy exists between an 18 year old adult and a 21 year old adult; however, since they are viewed by law as equals shouldn’t they have the same privileges? Obviously certain laws that regulate activities by age are necessary. Voting, alcohol, and driving should not be available to pe ople of any age because of the amount of responsibility these activities require. However the segregation between younger and older adults is unwarranted. Up until 1984 the legal drinking age was 18, however Mothers Against Drunk Driving (MADD) spurred a campaign to raise the age limit to 21. They succeeded with the passage of the National Minimum Purchase Age Act in 1984. (Shamed, Legal Drinking) The law aimed to lower the number of drunk driving accidents, which it has done, but only by a small margin. However, what it has also done is reduce the rights of citizens between the ages of 18 and 21. Americans hold personal freedom to be an undeniable right. The right to drink one’s self into a drunken state still falls under the personal rights category; however, this basic freedom is restricted by the implementation of the 1984 law. Instead of being able to have complete control over one’s life when they reach the legal age of adulthood, citizens are forced to wait an additional three years for an equal level of freedom. A need for drinking regulation definitely exists, yet it needs to coincide with other laws defining adult privileges. All rights would be gained simultaneously and lowering the legal drinking age to 18 would erase the discrepancy that now exists. Furthermore the temptation to undermine the law through underage drinking would be greatly decreased. For many college students that fall in between years of legal adulthood and legal drinking age, the desire to drink is spurred by getting away with something they are not supposed to be doing. According to â€Å"Dan,† an English exchange student, the typical college student would not feel the need to have a binge drinking party if he were allowed into the local bar. The need to throw private drinking parties would no longer be prevalent because the accessibility of alcohol would no longer be in question. Lowering the legal drinking age would also create a plethora of social events for those 18 and older. Currently many dance clubs are strictly for those 21 and over because the establishment serves alcohol. This leaves the remainder of the adult populous to find their own forms of entertainment, counter productive or otherwise. If these bored adults were allowed to participate in more activities there would be less people idling on the streets. Society as a whole would be better off because there would be less illegal activity taking place. This could entail underage drinking or more serious matters engaged by those with spare time and nowhere to go. .udc148834244687b24802efa428c1dda2 , .udc148834244687b24802efa428c1dda2 .postImageUrl , .udc148834244687b24802efa428c1dda2 .centered-text-area { min-height: 80px; position: relative; } .udc148834244687b24802efa428c1dda2 , .udc148834244687b24802efa428c1dda2:hover , .udc148834244687b24802efa428c1dda2:visited , .udc148834244687b24802efa428c1dda2:active { border:0!important; } .udc148834244687b24802efa428c1dda2 .clearfix:after { content: ""; display: table; clear: both; } .udc148834244687b24802efa428c1dda2 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .udc148834244687b24802efa428c1dda2:active , .udc148834244687b24802efa428c1dda2:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .udc148834244687b24802efa428c1dda2 .centered-text-area { width: 100%; position: relative ; } .udc148834244687b24802efa428c1dda2 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .udc148834244687b24802efa428c1dda2 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .udc148834244687b24802efa428c1dda2 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .udc148834244687b24802efa428c1dda2:hover .ctaButton { background-color: #34495E!important; } .udc148834244687b24802efa428c1dda2 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .udc148834244687b24802efa428c1dda2 .udc148834244687b24802efa428c1dda2-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .udc148834244687b24802efa428c1dda2:after { content: ""; display: block; clear: both; } READ: Human Proportions in Architecture Analysis EssayIf more young adults were drinking in public places as opposed to dorm rooms the possibility of excessive drinking would be lowered. The number of people present and the way in which bars and clubs are run provide the structured environment necessary to promote safer drinking. It is far less likely for someone to die of alcohol poisoning in a bar than in a private home because the number of people capable of recognizing alcohol related problems greatly increases. The adult population between the ages of 18 and 21 has been oppressed by the injustice of age based segregation for over a decade, and it is time for something to be done. The legal drinking age needs to be lowered to fit the remainder of the country’s standards of adulthood.
