(Two of the science experiments, I actually would not be brave enough to try at home, but watch them with your kids. They'll learn something and will probably love watching the explosions -- or maybe you're braver than I!)
1. Blow Up a Balloon with a Bottle and Pressure like Mom to 2 Posh Lil Divas.
2. Exploding Color Science Experiment with things you already have at home: milk, cookie sheet, food coloring and liquid soap. Science Bob explains why this works.
|Cover a cookie sheet with milk.|
|Add 6-8 drops of different food coloring drops, then add 5-7 drops of dish soap.|
3. Exploding Art (using a salad spinner) from Putti Prapancha.
4. Catherine Wheel Firework Craft from NurtureStore.
5. Classic film canister rocket using water (5 ml/1 tsp and Alka Seltzer). (If you can find a film canister!) Science Bob explains it fully here. Ours never quite worked (I think we have the wrong type of film canister), but Wild Thing had fun watching water fuzz from Alka Seltzer and loved playing with the water dropper.
6. Baking Soda/Vinegar Bubble Bombs - When we tried it the first time, we used a large zip bag, but that didn't work so well. The second attempt with a smaller bag gave the desired pop effect - the bag starts flat and then fizzes, expands and pops. This is simple and quick - and a great way to use all of the extra milk bags I have!
7. Soda Pop Bottle Rocket - Watch this Video Tutorial. All you need is a soda pop bottle, water and a bike pump (maybe some tape). This is really cool!! We can't wait to try it.
8. Tea Bag Rocket - Watch this Video Tutorial. This requires a match or lighter, so this must be done with strict adult supervision and should not be done near curtains! (As the lit tea bag rocket will fly up in the air). This one is also really cool, but I'm waiting until my kids are a bit older to try it at home.
9. Exploding Pinata made by a 7th/8th grade science class. (This activity includes gun powder and is best for a classroom setting, not a great DIY at home activity. Your kids will love watching the pinata explode, though, and will learn about the science behind fireworks.)
10. Dry Ice Eruptions/Bottle Explosions from Joe Genius. (These are also better watched then done, but the dry ice in a water bottle could be done at home in the proper setting with adult supervision).
