#Wow😳😲 from @melscience - How was your May? Let's look back on the most spectacular experiments of this month😄 #melscience #melchemistry #coolexperiments #AluminumCan #Cans #Wow #Amazing #Science #bestexperiments #thebest #scienceisfun #IAm_MsJohnson 💞 - #regrann https://www.instagram.com/p/BzhK8YrhC95/?igshid=6glqcnws9w29
from @melscience - Even easier, but just as effective! ⠀ Wrap the charcoal in a napkin and pulverize it with the hammer. Make some holes in the bottom of the plastic bottle. Insert some cotton balls, then add some charcoal. Cover with another layer of cotton balls. Your makeshift filter is ready! As the dirty water passes through the filter, the cotton ball layers trap the largest particles of dirt. Meanwhile, charcoal, with its myriad pores and crevices, traps the smaller pollutant molecules in a process called adsorption. The relatively large pollutant molecules “stick” to the charcoal’s surface, while the water molecules, minuscule in comparison, pass easily through the filter. This filter can cleanse water of large particles and some organic compounds but is powerless against microorganisms and heavy metals. Boil any filtered water to make it suitable to drink. #melscience #melchemistry #coolexperiments #diy #lifehack #waterfilter #purewater #surviving #IAm_MsJohnson 💞 - #regrann https://www.instagram.com/p/BzhJMjrBEut/?igshid=yr409dzk881p
#Repost @melscience (@get_repost) ・・・ Once you try it, you can't resist it 😉 Which trick is your favorite? ⠀ Rub the balloon vigorously on your hair to electrify it. Hold it a small distance away from your hair and observe how your hair is pulled to the balloon. Try the oatmeal experiment, and “pull” the balloon to your hand! All the objects surrounding us can be described as matter. Matter consists of atoms, and atoms consist of charged particles: protons and electrons (and electrically-neutral neutrons). Electrons carry a negative charge, while protons are positively charged. Usually, they balance each other out, keeping objects neutrally charged. When frictional forces arise between two objects, the surface-layer atoms of one object can give some of their electrons to the other object. The object that gives up its electrons becomes positively charged, and the one that accepts electrons acquires a negative charge. In our experiment, the balloon’s surface accepts some electrons and becomes negatively charged. An electric field appears around it, and attractive forces appear between the balloon and the positively- and neutrally-charged surrounding objects. Consequently, lightweight hair and oatmeal flakes are attracted to the balloon, and heavy objects, such as a hand, attract the balloon to themselves. #melscience #melchemistry #coolexperiments #safeexperiments #diy #balloons #tricks #fun #scienceathome https://www.instagram.com/p/BxKVq-BAHuy/?utm_source=ig_tumblr_share&igshid=1nnaofkg7gpyo
