Onetime, my 3 year old son, really enjoyed this activity. The hydrochloric acid in the cleaner will react with the aluminum to produce aluminum chloride and hydrogen, which will rise and inflate the balloon. Cl- ions can compromise the otherwise-strong Al2O3 layer around the foils surface and permit some copper ions Cu2+ in. Help remind students what copper appears like, to determine what theyre searching for. Around 212 degrees the water turns into steam and changes the starch inside each kernel into a superhot gelatinous goop. The soft starch inside the popcorn becomes inflated and spills out, cooling immediately and forming into the odd shape we know and love. Making Copper Powder BackgroundThe aluminum in aluminum foil reacts with copper sulfate and undergoes a single replacement reaction to create aluminum sulfate and copper metal:2Al + 3CuSO4Al2(SO4)3 + 3CuThis means that during the reaction, each aluminum atom loses three electrons to create an aluminum ion. Begin to heat the pan on a medium heat and add the popping corn. Now, using the flat bit of foil at the end from the water, crumple it right into a ball within the water.
