Maybe it'll also be a lesson on why not to drink Red Bull!
ReplyDeleteor a lesson in why to not drink milk o.0
DeleteThat's right
DeleteRedbull rocks
DeleteYep! My brother and cousins drink red bull like crazy! So while I am doing this project for school, I really hope this teaches them a lesson about the health concern around red bull!
DeleteHow much milk and how much red bull is being used?
ReplyDelete1:1 ratio
DeleteHello! I am a ninth grade physical science (physics/chemistry) teacher. I see that there is an error in your content on this page. Phase changes and states of matter are physical properties/changes. Causing milk to curdle is a chemical reaction making a precipitate. They are not the same thing. While it is a common misconception, please correct that on this site. I love all of the ideas on your site, but I had to say something about the content here.
ReplyDeletethanks for the heads up!
DeleteI'm a homeschooling mom; would like to understand this comment better but really don't get what Ashley is saying. Could someone explain more? (my kids are 10 and 7 and I was online looking for states of matter ideas for a science unit when I came across this site)
DeleteChanging from liquid to solid or liquid to gas or gas to liquid, etc. is a change in the state of matter (solid, liquid, gas). When the state of matter is changed, you are seeing a physical change, not a chemical change. Chemical changes result in a totally new substance forming during the reaction. Physical changes only change one or more physical properties (characteristics that describe the matter). When the solid is formed during this reaction, it is a totally new substance that is forming (a substance that was not there before the reaction occurred), therefore it is a chemical change, not a physical change.
DeleteAshley, Phase changes can be part of a physical or a chemical change. The phases changed, so it is a phase change. It also happens to be a chemical change because there was a reaction.
DeleteI think we're really getting into technicalities here. The red bull (acid) is causing the Casein (protein) to denature...or unfold from its structure. When this happens all of the casein in the milk starts to coagulate and clump together, which makes the Casein that was invisible before, become visible. There is a chemical change that occurs when the protein denatures...but the coagulation, clumping is not a phase change..it is the precipitate of the protein.
Deletelalaland...phase changes are always physical changes.
Love this. Cool Visual with the Red Bull Can; Vinegar will do the same thing (typically about 5% Acetic Acid) at a much lower price and you'll have lots left over for other experiments.
ReplyDeleteawesome!
DeleteI will be using this idea with my kids this week!!!!
ReplyDeleteawesome!
DeleteGross! :D
ReplyDeleteInteresting to think about with ice cream floats..... Do you have the whole procedure for this experiment written somewhere?
ReplyDeleteDoing this with my 5th graders tomorrow! Thx! Does anyone have a lab sheet to go with it?

ReplyDeleteThe experiment can continue further ......acid is added to milk anyway a process in cheese making. It was a means store milk a perishable due bacteria- long before processes refrigeration, pasteurization or homogenization (all stabilized raw milks life beyond 1-3 days pending holding temperature) Increase shelf life curdle enter fats such as cream, butter & buttermilk enabled 3-5 days final mold cultures such as penicillin (mold that inhibits bacteria) it enabled shelf stability milk proteins weeks to several years. This depends upon the mold cultures now there are bacteria cultures that are safe to consume and extend milk use such as souring bacteria: yogurt, sour cream and creme fraiche - requirement sour bacteria requires fat solids for shelf stability. Mold is the most durable in milk food stability and prized especially aged cheddar producers due higher values some the oldest sold & consumed 28-40 years old.
ReplyDeleteYou can continue this science experiment towards the direction application food supply storage, innovation food science to prevent starvation and human health introduce works Dr. Louis Pasture & Dr. Alexander Fleming.
May I suggest make it better experiment if kids can see the purpose application via eating it there are safe-tested recipes make homemade kitchen: cheese, butter & yogurt. Yes there are easy to follow kits for all three under $30 butter is quick under 20 minutes the others longer due passive wait times so best done end day then over-night to mature ready the next lesson day. Some kits come graded as beginner & age level ----I learned via great aunt's farm over 37 years ago committed to memory as determine freshness & fresh tastes best! :)
Wow crazy experiment... Chemistry and pharmaceuticals are just most amazing things in the world! <3 it
ReplyDeleteThis is an awesome experiment. Great Job!!!
ReplyDeleteHey, I get it. In second grade, which I have taught, it is mostly about getting them to see the experiment, why we do experiments, the job of a scientist, and how to manage your behavior during an experiment. It's an awesome experience for the kids and it brings something a little more readily available to them rather than the vinegar as suggested above. It also has to be safe for the kids to use. Great job. Can't wait to use it. Thanks
ReplyDeleteSave some dough--buy a Red Bull, drink it, and put vinegar in the can to use for your experiment/demo. Any acid will react with milk this way, including the Acetic Acid in Vinegar--and it'll happen faster!
ReplyDeleteHow will whole milk combined with milk differ from fat free combined with milk? We did this and saw more curdles at the bottom of the Coke bottle, but don't know why.
ReplyDeleteNow you know why your tummy feels a bit strange after drinking a red bull, when you ate cereal for breakfast :-{
ReplyDeleteI have heard people say this will work with vinegar. Will it work with other types of soda? Or apple cidar vinegar? It looks like we will be trying these out.
ReplyDeleteThis youtube video is a hilarious example of why you should not drink this stuff. I was laughing pretty hard. https://www.youtube.com/watch?v=RjWtv-ih6Z8
ReplyDeleteCool my dad is the boss of Redbull

ReplyDeletei like trains
ReplyDeleteInteresting that so many adults (parents?) are saying not to drink the Red Bull.
ReplyDeleteBut as stated more than once, vinegar works just as well. And without trying it, I bet almost any fizzy drink will also work the same (e.g. CocaCola, Pepsi, Mountain Dew etc).
In fact, cow's milk is not particularly good for the human body, especially as it promotes mucus in the system. And don't start talking about the calcium because there are other ways to get calcium - e.g. cheese (which doesn't seem to promote mucus in the same way or to the same extent).
I would have liked to see this experiment continued with various other drinks - e.g. Coke, Mountain Dew, "V", maybe even beer, to see what effects those have instead of just picking on Red Bull.
