What would be the thrill that children get when they get everything perfect in their first trails!? Not much right! So, give it a try with Lego pieces and have a ton of fun while learning simple physics.

#Marshmallow catapult trial

This is a great STEM practice that offers trial and error method of learning which actually makes this Lego activity more fun and interesting. Let us turn their fun play with Lego pieces into a fun STEM activity of making simple catapults. Playing with Lego pieces promotes fine motor skills and works as a wonderful exercise for little fingers.

Learn how to build PVC Catapult so easily by clicking on Make a Simple Catapult using PVC Pipes 6. This encourages critical thinking in kids. Ask your children how PVC Catapult works and analyse the physics how effectively it works like other catapults. Master your kids in building simple and effective catapults using PVC pipes creatively. Make sure you don't pull too far back on the spoon when you're launching your marshmallow as you might break the skewer or the spoon.I found this idea of making PVC Catapult an excellent way to engage pre-schoolers and high schoolers to STEM and Engineering design challenge. You need to pull the spoon back far enough to slightly stretch the rubber band.

Place a marshmallow on the spoon and pull the spoon back to launch.

Pick 1 of the 3 triangle points and push the skewer with the spoon into that marshmallow. With the rubber band attached to the peak of the pyramid, put the spoon and skewer through the center of it.

Put your spoon and skewer through the rubber band and into a marshmallow.

This is the first part of the catapult mechanism.

There's no need to wrap this rubber band tightly around the pyramid as this rubber band won't be used to hold the pyramid together. This rubber band will hold the catapult in place.

Put a rubber band loosely around the peak of the pyramid.

Wrap the painter's tape around the skewer a few times to keep the spoon attached. The head of the spoon should extend past the skewer. Line the body of the spoon up with the skewer and hold it in place with your hand.

Use painter's tape to attach your plastic spoon to another skewer.

Wrap painter's tape around the marshmallow and top of the skewers to hold the parts together. For extra security at the peak of the pyramid, use either tape or rubber bands to hold the skewers and marshmallow together so they don't come apart when you use the catapult.

Use tape or rubber bands to secure the peak of the pyramid in place.

Where the 3 skewers meet the marshmallow is the peak of the pyramid. Bring all 3 of these skewers together in the center, pushing them all into 1 marshmallow, around halfway through.

Push 1 skewer into the top of each of your marshmallows on the triangular base. Make a pyramid shape with 3 more skewers and 1 more marshmallow.Standard-sized marshmallows will work best but you can use mini or jumbo marshmallows too Connect the skewers at each corner with a single marshmallow. Lay out 3 skewers so they form an equilateral triangle on a flat surface. Create a triangular base by sticking 3 skewers into 3 marshmallows.
