Aim: To see which bubble gum makes the best Bubbles, has the best elasticity and keeps its taste for the longest.

Hypothesis: I think that the ? will make the largest bubble and have the longest stretch. The ? will have the longest taste.

Equipment:

• 3 different chewing gum brands
• stop watch
• ruler
• graph to record detail.

Method:

1. Place the first piece of chewing gum in your mouth and time how long it takes to keep its taste.
2. Chew the gum and record this time on the chart.
3. Using the same piece of gum blow a bubble. Record on the chart as 'no bubble', 'small', 'medium', 'large'.
4. Test for elasticity. Keep all of the gum in your mouth and see how long you can stretch it. Measure it and record its length.

Type of gum	Taste	Bubble size	Length
Hubba-bubba	1m 19 sec	mediem	63cm
Extra	3min+	small	33cm
PK	3min+	Small	55cm

Hubba-bubbas taste went for 1m 19sec but it was the biggest in size and length

Extras taste was 3 min+ it had a small bubble and a stretch of 33cm

PKs taste was 3 min= its bubble was small as well and it had a stretch of 55cm

Hubba-Bubba is the best gum to buy if you were wanting to blow bubbles and stretch but for the taste it would be Extra or PK
