"Ice Tunnels" combine ordinary salt, ice and liquid watercolors in an unforgettable art and science experiment that costs only pennies. Try this on sunny day with lots of bright sunlight and you'll experience amazing color, light refraction and salt crystallization with a hands-on experience for children of all ages. @Christie Moffatt Moffatt Moffatt Moffatt DeSilva - saw this and thought of you and your kiddos!
We love exploring the vinegar/baking soda reaction in pre-school, so kids should be experts by the time the warmer months roll around! How about trying the experiment using frozen vinegar cubes in a water table full of water/baking soda solution! Interesting sensory and science play for a hot day! Definitely worth a shot!
