Warn­ing! Only un­der adult su­per­vi­sion.

Reagents and equip­ment

  • dis­pos­able cups;
  • bak­ing soda;
  • vine­gar;
  • food col­or­ings.

Step-by-step in­struc­tions

Add var­i­ous food col­or­ings to some cups of bak­ing soda. Then pour some vine­gar into each cup. Watch as the mix­tures erupt in an ex­plo­sion of col­or!

Process de­scrip­tion

Bak­ing soda re­acts with vine­gar, re­sult­ing in the for­ma­tion of car­bon diox­ide. The gas is re­leased so rapid­ly that the mix­ture residues foam up and burst out of the cups, re­sem­bling a se­ries of vol­canic erup­tions! The food col­or­ings make the foam even more beau­ti­ful!
