Pudra portocalie este dicromatul de amoniu. Când este încălzit, formează azot gazos, apă şi oxid de amoniu, adică pudra neagră similară unui vulcan ce poate fi observată în imagini.
Acele tentacule sunt reacţia ce apare ca urmare a arderii tiocianatului de mercur. Substanţa solidă de culoare albă se extinde când este încălzită şi se transformă într-o masă neagră, similară tentaculelor ca urmare a descompunerii nitratului de carbon. Această reacţie este cunoscută drept ”şarpele faraonului”.
