A popsicle stick catapult is a great science project for those rainy days.
It could also be a great craft activity for father's day - which father would not enjoy building a catapult with his son or daughter? Of course, mothers would equally enjoy it!
You don't need a lot of things to build the catapult, most of you will have all the items at home already.
What you need:
1. Make a stack of five popsicle sticks. This will become the base.
2. Use two of your rubber bands to fix them at each end.
3. Join two sticks together at one end and fix them as shown in the picture.
4. Split the two sticks over the base and secure them with another rubber band.
5. Glue the bottle top on as shown in the picture.
Your catapult is now ready. All you need now, is something to launch - a small soft ball or similar item will be ideal!
This project is also ideal to get your child to understand that different items react differently when launched. You can turn it into a little game of who manages to catapult items the furthest.
Should you decide to give this project as a gift on Father's Day, I would suggest you give all the items including the instructions to the father and child - this will get them to spend some time together building the catapult. You could put it all into a little box and wrap it up as a nice present.
Afterwards putting it all together, they can have even more fun trying to hit certain targets around the house! My husband and son particularly enjoyed launching small soft balls at me! :-)
