“Bath bombs” experiment

How to make a bath bomb from soda, salt and citric acid

How can you make a bath bomb in 15 min­utes? It’s very easy, you can find all the in­gre­di­ents in the kitchen! In this life­hack/ex­per­i­ment, we’ll show you how to make fizzy bombs from soda, salt and cit­ric acid.

Reagents and equip­ment:

  • bak­ing soda (200 g);
  • cit­ric acid (100 g);
  • salt (50 g);
  • olive oil (24 ml);
  • es­sen­tial oil (0.5 ml);
  • food col­or­ing;
  • wood­en spat­u­la;
  • ice tray;
  • glass bowls.

Step-by-step in­struc­tions

Place bak­ing soda, cit­ric acid and ta­ble salt in a large bowl. Stir the dry mix­ture thor­ough­ly. Di­vide the mix­ture into two parts, to make bombs of dif­fer­ent col­ors. As a mois­tur­iz­ing agent, add olive oil, and es­sen­tial oil to pro­vide an aro­ma. Add the food col­or­ing and stir the mix­ture thor­ough­ly. Pour the mix­ture into the ice tray and place in the freez­er. In 10 min­utes our bombs are ready! You can throw them into a hot bath and en­joy the col­or­ful and aro­mat­ic bombs fizzing in the wa­ter.

Pro­cess­es de­scrip­tion

The bomb con­sists of cit­ric acid and bak­ing soda. When the bomb dis­solves in wa­ter, sub­stances be­gan to re­act among each oth­er and re­lease bub­bles of car­bon diox­ide. So the bomb seethes and hiss­es.
