Bubble art and explosions

My dear husband brought home 20lb of dry ice... We spent the whole weekend doing every possible (yet safe) experiment.

Here's our favorite one - bubble art. 

You probably know that if you add dry ice to a bowl of soapy water, you'll get a lot of bubbles. Well, if you add food coloring to the soapy water - you'll get some colored bubbles. You've got an idea.

Here're more detailed instructions, just in case.

Put some dish soap in a cup, add warm water. Mix. Add a few drops of food coloring. Mix. Add some dry ice, stir a bit. Wait for the bubbles to form.

Take a piece of paper - press it onto the bubbles. Let dry, enjoy your "bubble" paper.

If your kids like explosions better than art, here are some safe ideas:

- film canister - the lid pops with a bang, it seldom flies off. (safe for home, just point away from people or breakable things)

- a plastic zipper bag - put it on the floor, watch it inflate and then pop. It's easier to handle than a balloon, but just as much fun.

- milk/juice tetra pak with a screw on cap (better to do outside as it may splash) - it makes a loud bang, the top seam breaks apart. No flying debris.
