When the primary sevens where away we made bottle rockets. We got all of the things we needed. We needed a bottle something to make the wings out of, a cone ,a pump, water and a cork.

We got the bottle and glue gunned the wings to it so that it will go higher. We then got a bit of paper and cut a circle and made a cut into the middle and made it into a cone. And we stuck it on the bottom we the decorated it a little. We then made stand for it we had a cup and cut a hole in it and pushed the pump through we then had to put some marbles to weigh it down.

We then took it outside and before we filled it with 500 ml of water then put a cork with a hole in it in the bottle and then we attached the pump to it. You have to pump it quick and fast and then it shoots up to the sky.

Bottle rocket

When the primary 7s were away the 6s made a bottle rocket it worked pretty well. We brung in a bottle each but we ended up doing the one we got all the materials we needed then started.

We needed a 2l bottle, a cone out of card, a strong material for the rocket wings, a cork and a pump. We used a glue gun and stuck the wings on the bottle we cut a circle out of card then put a cut into the middle. We used duck tape and used seletape. To stick the cone into the bottle of the bottle and checked it was the right size. Both of us had to make something to keep it standing so we used a full tub of marbles into the cup. We put a hole onto the cork so it was the right fitting for the pump. One of us hooded the rocket and the other one of us put 500ml of water Into the bottle.

Then we took it outside and took a few attempts it worked but every time Mr. Johnston had done it it went higher and higher the last time when the primary 2-5 came out.
