- Egg in a Bottle
Take a bottle with a narrow opening. Light a piece of newspaper with matches and drop it in the bottle. Quickly place a hardboiled egg on top of the bottle’s opening to have it sucked into the bottle.
- Homemade Glue
You will need to pour one cup all purpose flour in a container. Add half a cup of water to it. Mix well to avoid lumps and till you get a pasty consistency. Try it out on some newspaper or the kind of paper you would like to glue together.
- Balloon Rocket
Get a long piece of string. Secure one end to a wall or pole with tape and leave the other loose. Now blow a balloon and hold the end to avoid the air from escaping. Tape a straw to the balloon. Pass the thread through the straw now release the balloon for an air powered rocket.
- Bendy Bones
Save a chicken bone after dinner and rinse it clean. Try bending it you won’t be able to because it’s pretty strong. In a glass jar, place the bone and fill it with vinegar covering the bone completely. Cover the jar and leave it for 3 days. After 3 days you will be able to bend the bone easily.

Few safety precautions:
Before attempting any of these science experiments, please make sure that your kids put on safety glasses, gloves, etc, especially with experiments dealing with dry ice. Dry ice must not be touched by bare hands nor it should be placed on the skin. Also, be very careful with experiments that involve fire. Keep fire extinguisher and a bucket of cold water at hand, while doing any experiments with fire. The best way is to not to let your kids do any fire experiments. Instead, you show the experiments yourself.
