1. Which bubble bath
bubbles last the longest
and does heat make a
difference?

2. Hypothesis-what I think
might happen
I think the Raspberry bubble bath will last the longest because it has a
long resistance label but think if I put shampoo in the bath it will go
away, because when I’m in the bath the shampoo make’s the bubbles
disappear.
I think the heat will change the mount of bubbles that are produced as I
mix it. I think the cold water will make the least bubbles

3. Test-Materials
• Raspberry bubble bath
• Blue berry bubble bath
• Wild rose bubble bath
• Warm water for the bubbles.
• Four different Icecream containers
• Glycerol (in an extra test thats not in these tests!)

4. Test - Method
I will measure how many bubbles last after 1/2
hour and 1 hour.
I will then do a separate overnight trial
1. Place our four pots on a flat surface.
2 .Label the pots blueberry, raspberry, strawberry and homemade.
3. Next put the raspberry, blueberry, strawberry and the homemade
bubble bath in a different pot.
4. Add warm water to four pots and stir till bubbles appear.
5. Leave for half an hour come back and check the label and inside the
pot Count the bubbles.
6.Check again after 1 hour, and again in 1 and 1/2 hours
7.Test 3 times.

5. Result
Our first test on the bubble bath. We let the bubbles rest for 1 hour. After 1
hour we decided that wild rose had the most bubbles left.
Blue berry and raspberry had the same amount of bubbles but had less
that wild rose.
The home made bubbles didn’t have as much bubbles as the others but it
was pretty close, I think because there was lots of shampoo in it.

6. Result
DAY 2 Tested again and we got a completely different answer.
This time our hypothesis was correct raspberry had the most bubbles
left. Blueberry had the lest amount of bubbles. Wild-Rose had the
second most amount of bubbles.

7. Result
Day 3 we tested again and wild rose had the most bubbles, but only by a
small margin. Blue berry was next with a tiny bit less than wild rose. Then
behind that there is raspberry.

8. Conclusion
My hypothesis was incorrect Raspberry didn’t have the most bubbles left in all three tests, but did in the second.
Wild-Rose had the most bubbles left twice in the first and in the third test.
The blueberry didn’t have the most in any of the tests.
I figured out that by adding 1tsp of glycerol to the bubbles the bubbles will last longer. I found out that it is good
for your skin and also makes more bubbles last longer.
Temperature Trial
Conclusion based on average
BUBBLE BATH
The warm water after 1/2 an hour at 38 degrees had the most bubbles and they lasted the longest.
Hot water - Bubbles covered 23.3% of the water surface
Cold water- Bubbles covered 10% of the water surface
So Bubbles last longer in warm water over half an hour. That’s about how long I am allowed to spend in the bath
So I will ask mum to buy the Wild rose bubble bath for my bath times.

9. Why I chose to do this
• I wanted to find out how to make the bubbles in bath last longer because my little
brother and sister are always complaining about the bubbles disappearing out of the bath.
So I wanted to fix it and now I have. We will now add some glycerol to the bath to make
the bubbles last longer.

10. In future reference
• I will add another four cups of warm water and keep the amount of bubbles at 1 tbsp
and see if that will make a difference to how many bubbles. I will also mix the
bubbles for a lot longer than I have been.

11. Temperature trial
Try using colder water rather than warm water.
Today I tested the effects of different temperatures on the bubbles.
Trial 1
I used the wild-rose bubble bath and 4 cups of clod tap water (16 degrees)
Trial 2
I used 1tbs wild-rose bubble bath and 4 cups of warm water (38 degrees)
Trial 3
I used 1 tbs of wild-rose bubble bath and 4 cups of hot water (50 degrees)
I found out that the warm water (38 degrees) had the most bubbles left.

12. GLYCEROL Test
• Trial with glycerol added with the one that had the most bubbles after test 3. This
was the Wild-Rose bubble bath.

13. Shampoo trial
We trailed with the shampoo I thought the shampoo made the bubbles disappear.
BUT! It didn’t! I was amazed! The bubbles were the same as the other without
shampoo in it.

14. My research Questions For the Man at Jeymar
(SOAP MAKER)
• How does shampoo make bubbles disappear?
Shampoo doesn’t, it’s the dirt the shampoo pulls out of your hair!
• Whats the difference between liquid soap , shampoo, and bubble bath?
Nothing!
• How much work does it innovate?
10 hours/ a day everyday in the early spring for christmas and summer hotels!

15. Jeymar and the history of soap -Research
#history -mens mw - burn wood - put in big fill and pitch fork when a feather
dissolves ready to go!
Now days - caustic soda (40%)
palm oil (hard) , coconut oil (bubbles) & olive oil (creamy consistent)
Heat until liquid. Add 2/3 oil 1/3 caustic.
Note Temperature is important!) Aims for about 50 degrees - to mix them you will
need a mini electric beater. It will liberate lest in the reaction. Mix until “trace”
where “dint” remains when you take the beater out . Then quickly add avowers-
don’t sliv too much - pour into mould. after 24 hours ready to leave and age.
- Glycerol ^ bubbles cos it dries and cracks it needs water surface tension
- If the soap dries it will crack.
- Essential oils _ the steam from boiled Aolnts e.g. blend and you will find it contains
oil.
4m3 of rose petals to make 1mL of rose essential oil.
