This is really fun and easy and the kids think it is the best thing since sliced bread. We did it at the cottage using a kit but Pancakes & French Fries shows a simple way to do it at home using tape.
|Image & Idea: Pancakes & French Fries|
- 2 L bottle of Diet Coke
- 1 package of mentos
- scotch tape
Following the instructions at Pancakes and French Fries you will tape your mentos together, drop them into a bottle of Diet Coke and stand back while the mentos work their magic.
Rainbow Bubble Snakes:Kids love bubbles but these are extra amazing because they come out as a rainbow. They are also a great way to get the kids into recycling.

- empty plastic bottle
- old sock
- elastic band or duct tape
- dish soap
- food colouring
Instructions:Tammy at Housing a Forest has great photos and instructions to make these fun bubble snake makers. They can be put together in minutes and the kids can do most of the work.
Ivory Soap Explosion:Got two minutes? This one is fun because the kids can try to predict what is going to happen when you put a bar of soap in the microwave but I doubt many of them will guess this result.

- bar of Ivory soap
- 2 minutes
Instructions:The instructions for this one are pretty simple, take a bar of Ivory soap and put it in the microwave for 2 minutes. That being said, I highly suggest you pop over to Fit Kids Clubhouse to see the great questions Ms. Liz asked the kids as they were doing the experiment.
Jellyfish in a Bottle:This idea is so cute and unbelievably realistic looking. By combining a plastic grocery bag with some coloured water and an empty bottle you can create a jellyfish that is ocean worthy.

- transparent plastic grocery bag
- empty plastic water bottles.
- blue food coloring
Instructions:The step by step instructions including photos are incredible at BhoomPlay. Also take a moment to watch her adorable video of the jellyfish at play. You will understand quickly why the kids love playing with them.
Burping Bags:What kid doesn't like burps? These bags grow fatter and fatter until they finally burp open and all it takes is a simple and safe science experiment to make it happen.
|Image & Ideas: Preschool Powol Packets|
- 1/3 cup vinegar
- 1/4 cup warm water
- sandwich baggies
- 2 tablespoons baking soda
- 1-ply paper towels
- food coloring
- glitter (optional)
The key to this experiment is keeping the baking soda safely wrapped in the paper towel and gently placing it in the bag that already has the vinegar and warm water. Preschool Powol Packets has fabulous instructions and photos to show you how to do this, step by step.
Bouncy Eggs:This is a fun experiment for kids because they all know how fragile an egg is and find it hard to believe that they could actually bounce. It is true though and with a little patience (about 3-4 days) they will be able to test this out.
|Image & Idea: I Can Teach My Child|
- mason jar
- white vinegar
Instructions:You need to submerge the egg in vinegar for 2 days, then empty the vinegar and replace it with fresh vinegar and leave it for another day. At the end of 4 days the shell will have dissolved and the egg will bounce if dropped from about 5 inches. Don't drop it on the ground though...they can still break. The science behind this experiment is explained at I Can Teach My Child.
Kids love balloons and they especially love seeing them being blown up before a party. Why not make a party of your own and blow up some balloons without
Inflate a Balloon Without Blowing it up:
