Handleiding

Here’s how it continues:

Heat half of the gum base in a

microwave-safe container. The

sticky gum base will leave a

residue that will be difﬁcult to

clean out of the container, so you

may want to use a disposable

container if you do not want to

spend the time cleaning it.

Start with one and a half minutes

(90 seconds) at high power and

then check to see if the gum

base has softened. Continue to

microwave the gum base in 30

second increments until the

gum base has melted into a thick

gooey liquid. This may take up to

ﬁve minutes in the microwave. Be

careful removing the tray from

the microwave as it is hot.

Cut the corner off of one of the

ﬂavor packets. Pour all of the

ﬂavor powder and about half

of the powdered sugar onto the

melted gum base.

Cut the corner off of the corn

syrup packet. Pour half of the

corn syrup onto the melted gum

base.

Mix everything together with the

spoon. The mixture will become

very sticky. As it cools, the gum

base will also become more solid.

TIP!

To clean the spoon and container after

the experiment, use hot water to melt

the gum base again.
