It’s very interesting when you can play with your kids and teach them something. So today we offer you to make a funny scientific project! For this activity you will need cupcake liners, sponges, scissors and Mr. Bubble original foam soap for “frosting”. Use the bottom of one of the cupcake liners as a template to cut the sponge into two circles for each cupcake liner you are going to use. Head to the tub with your cupcake liners and sponge circles. For bubbles add a few drops of Mr. Bubble 3in1 or Mr. Bubble original bubble bath under the running water, it will set the stage for the perfect tub laboratory. The next steps of the instruction are here.
