I'm making a machine to apply sunscreen to your back.
I love playing outside but I hate putting sunscreen on.
I can't reach my own back.
Ew! Mom, no!
I've got long arms and even I find it hard to reach my own back.
It's kind of awkward asking someone to do it for you.
This is a universal problem and we need to solve it.
I'm taking this.
Sweet.
We've put these mirrors for me to see my back
because the idea is to be able to put sunscreen on my own back.
Your back is a bit slanted.
Oh, there we go.
It's just slipping.
It can't get traction. Here we go.
We lost the sunscreen!
It's still working, it's good!
The car falls off my back because it's not flat.
It won't solve AJ's problem
but our expert contraptionist Brett has a cool idea
to apply sunscreen to the whole back instantly.
Okay, here it goes.
I'm filling it right up this time.
Now we have like twice that we had last time.
Let's try it.
3, 2, 1...
What do you think? Does it work?
It splattered it all over you with no even coverage.
- Yeah. - You'd be a bit covered
but you'd still get sunburned.
The sunscreen cannon isn't perfect, I think we can do better.
You have to reapply sunscreen every 2 hours.
It's hard to remember if you're having fun.
AJ's machine's gonna be made with beach stuff
and is gonna reapply even if he forgets.
It's gonna start with lifting the lid of the chilly bin
which will knock over a sand castle
and will set off the machine.
I'm not good at sand castles.
Perfect, that's what we're here to do!
We wanna build a sand castle right underneath
that holds the ball in place
and then gets knocked down by the water.
Okay, sweet.
- Makes sense? - Yeah.
- Look, we're halfway up! - Damn!
And... go.
Look how close it is!
- Yes! - I hope it won't collapse.
We're so close.
- It's sweet. - So much build-up to this moment.
- We've been here for... - 4 hours.
The ball is held in place by the sand castle.
3, 2, 1...
It's going!
It kinda worked!
My gosh, we did it! High-five!
- Great, but I won't do it again. - Me neither.
We could try making a smaller sand castle at the bottom
that we can pour water through, and put for example a flag on top.
- And you can make it in 5 minutes. - Yeah.
Rather than 3 hours.
A small sand castle with a flag that holds up the ball.
AJ hates when his mom puts sunscreen on his back
so we're gonna use spray sunscreen.
We have a wooden wheel.
The hole is normally right in the middle
but we've off centered it a little bit
so that as it rotates, it's gonna push down on the button.
It should drop and rotate in a circular pattern
spraying my back with sunscreen.
It feels nice.
Okay, I need to stop it.
It's mostly at the bottom, a bit at the top.
It's not gonna work
but I have an idea for better coverage.
Okay, dropping weight. Now.
Oh, it's cold!
It needs to be heavier.
Dropping...
Oops, we broke our rig.
- We've put on 3 kilos now? - 3 kilos, yes.
Okay, go.
Wait, leave it! Let me see if I bend forward...
It's limited success.
It gets stuck at this part.
We've modified it by adding a spring
so it can get over my shoulder blades.
AJ is coming and I really hope the machine works.
Oh wow!
Oh my goodness!
- You weren't expecting it. - No!
We didn't test it yet but I'm getting sunburned, should we try it?
Sure. Hope it works.
What do you think AJ? Would you use the machine?
Oh... Uh, no.
Okay, well we tried.
Perfect!
