Start attaching-pebbles use hot glue,but if little hands are sticking them down, you can also use a super-strong double-sided tape, such as the type used to lay carpets. It’s entirely up to you how closely you’d like to pack those pebbles, as the grouting you’ll use to finish the effect will fill in any gaps.
Popped Bubble Art: I've done this activity with my kids a few times now and it never fails to fascinate them - and me! Simply color bubble mix with food coloring and blow bubbles onto paper - as the bubbles land and pop, they create beautiful works of art. It goes without saying that this project is best done outdoors. A great one for those lazy summer afternoons.
