“Levitating soap bubbles” experiment

Home experiment with vinegar and baking soda

Have you ever dreamed of con­trol­ling ob­jects by telekine­sis? In this ex­per­i­ment, you’ll find out how to make bub­bles float in the air.

Safe­ty pre­cau­tions

Per­form this ex­per­i­ment un­der adult su­per­vi­sion.

Reagents and equip­ment

  • con­tain­er;
  • sodi­um bi­car­bon­ate;
  • 9% ta­ble vine­gar;
  • soap bub­bles;
  • large beaker.

Step-by-step in­struc­tions

Sprin­kle sodi­um bi­car­bon­ate into a beaker and add vine­gar. Wait one minute. Care­ful­ly pour the re­sult­ing gas into a con­tain­er. Blow some soap bub­bles into the con­tain­er and watch!

Pro­cess­es de­scrip­tion

Sodi­um bi­car­bon­ate re­acts with vine­gar, re­leas­ing car­bon diox­ide. car­bon diox­ide is heav­ier than air, so it is easy to pour into the con­tain­er. Soap bub­bles are mere­ly air en­cased in a soap mem­brane, and thus don’t sink in the con­tain­er – they are “sup­port­ed” by the in­vis­i­ble car­bon diox­ide.
