Make a bubble snake

We don't drink much soda so when hubby finally brought a Pepsi home I snatched up his empty bottle quicker than a hungry child grabbing at freshly baked Christmas cookies.

Why?  Well, I had been dying to make a bubble snake blower. And honestly, could you blame me?  Look at the long foamy chain of bubbles I was able to blow.

Wowzers.  This photo makes my inner child squeal with delight

To blow awesome foamy snake-like bubble chains, I just needed a couple of materials:

Materials:
- empty plastic bottle
- wash cloth
- scissors
- rubber band
- dish detergent
- water
- plastic container

Directions:
1.  Cut off the bottom of the bottle.
2.  Cut a circle out of the wash cloth that's about 1-2 inches larger than the bottom of the bottle.
3.  Use a rubber band to attach your washcloth circle to the bottle.  That's it!
4.  Dip the bottle (wash cloth bottom) into dish detergent that's been mixed with a bit of water.
5.  Blow.  A foamy bubble snake will appear before your eyes.

(Warning:  Do not inhale, only exhale. Otherwise you'll end up drinking dish detergent like I did. Yuck.)

Here are some photos of Baby Chuck and I playing with our bubble snake blower.  (You may be wondering why we're in the bath tub.  Or why my bathtub is so dirty.... Hmm..  Well, we fully intended to blow bubbles outside, but it was just too cold.  The bath tub served as a nice place to try the activity out, since the bubbles created quite a sticky mess on the ground.  As for why my bathtub  is so dirty... I've neglected to clean it.... eek.)




Let me know if you try this out with your kids.  I can't wait till the weather gets warmer.  We'll definitely try blowing more bubble snakes outside.

Make your own rainbow flowers

Last weekend, I made these rainbow flowers.
Aren't they purty?

Fun with food coloring, soap, and milk

We've now had 2 days of cold and wet weather.  Baby Chuck and I try to go out in the mornings, but we usually stay at home in the afternoons because parking spots are so difficult to find.  (Curse you, parallel parking!)

So... what's a cooped up mama and 16 month old baby to do?

Well, yesterday we tried another food coloring activity.  This time we found Steve Spangler's amazing science page.  He had a demonstration that involved food coloring, dish detergent, and milk.   Look what we were able to do:

Ooh.  Psychedelic!



Materials:
- milk  (we used whole... but I bet you could use other types of milk... but the intensity may differ...)
- bowl / container
- food coloring
- dish soap
- cotton swab
