These two making activities are a fantastic way to share a transport interest with an older child whilst introducing them to some fantastic science experiements about forces and chemical reactions.
Make your own car
You will need:
- 4 milk bottle tops. Pierced in the middle to put onto a cocktail stick.
- 5 cocktail sticks
- 2 thick straws
- 3 elastic bands (1 medium, 2 small)
- Glue gun
- Place two marks on both of your straws at 1 1/2cm and 2 1/2 down from both ends. This is where the cocktail sticks will go.
- Pierce the cocktail sticks through the marks to bring the straws parallel to one another, about an inch apart.
- (Check that the bottle lid will fit onto one of the sticks as you may need to bring the straws closer together.) With the glue gun, secure the inside cocktail sticks to the straws, just on the inner side. In addition to this snip the end off of the remaining cocktail stick and glue this to the middle of one of the outside sticks, in order to make a hook. (You must make sure its short enough for the cocktail to rotate round fully.) Snip the edges of the glued cocktail stick as close to the straw as you can.
- Attach the first elastic band to the opposite inside stick to the end you’ve made the hook. And attach the other two bands one at a time to the first using a square knot.
- Fill the wheels with playdoh so that they have some weight to hold them down.
- Place car on hard surface. Pull elastic band so it goes over the hook. Wind that stick backwards as if a wind up car. Your elastic band should be winding round the stick as you turn it.
- Finally let the car go and watch how far it speeds away from you.
Make your own rocket
You will need:
- Elastic band
- 3 rocket wings (with tabs)
- White vinegar
- Cling film
- Bicarbonate of soda
- Make your rocket wings with a flat bottom so it helps the rocket to stand.
- Essentially your rocket is an upside down bottle. Turn the bottle upside down and tape the wing tabs to the bottle nearest the opening, with the bottle being high enough to have a balloon under it.
- Make a cone with the paper and attach it to the top of your rocket.
- In a 10cm width of cling film lay several big spoonfuls of bicarbonate of soda and then fold it all up so the powder is secure. Leave to one side.
- Pierce a hole in the very top of the balloon.
- Fill between 1/4 and 1/3 of the bottle with vinegar. Lay it down carefully!
- Insert the bicarbonate of soda into the bottle wilst still led down until it is just inside the mouth ofnthe bottle. You need to be gentle and keep bottle led down so that you dont have an explosion when you are not ready.
- Again, carefully place balloon over the mouth of the bottle and secure with elastic band.
- Get everyone ready for take off-this could happen very quickly. Place the rocket where you want it to launch, stand back and watch your rocket blast off!
