Just as you can tweak the physics of an object, so too can you adjust the properties of a material that you place in one of your levels. This is very exciting, as it means your sack person can climb and grab things they otherwise wouldn’t be able to.
Ascend the platform on the left, and leap off of it onto the yellow platform (which is bouncy so your sack person can leap onto the next area). Once safely across, move your sack person into the foreground a little, and return back to collect the White Fluff Decoration Prize Bubble before proceeding.
Up ahead, use your Popit Cursor to select the Material Tweaker, and then press 
to start adjusting. Make the orange object grabbable. Now, your sack person can jump and grab it with 
to ride it across the long, spikey gap of death without dying.
Next, your sack person faces a very tall orange wall, with some Prize Bubbles to be had. To climb it, you must first make it climbable using the Material Tweaker. Then, make your way to the top to collect the Moss Rock Decoration and Margin Doodle 2 Sticker on the way to the next platform.
Creating Some Friction
It’s time to talk friction. This can be a huge help if your sack person is trying to climb a surface that would otherwise be slippery. Try it out on the orange ramp up ahead. Select the Material Tweaker with your Popit Cursor, press to start editing, and then increase Friction to 100%.
Proceed down the icy ramp up ahead. At the bottom, take a leap of daring faith to collect the Prize Bubbles for the Vinyl V Stitching Material and Set Square–60 Degrees Decoration as your sack person makes it over the gap.
Laying Down the Material Tweakers
Now that you know the basics of how Material Tweakers work and some of the wondrous things they can do for your objects, you’re probably itching to place some of your own.
Go ahead and start with the orange platform up ahead. Press or the touch pad button to open your Popit, then select your Tools bag. Inside, you can find your very own Material Tweaker, which you can place on any orange item you see now. Use it on the orange platform to increase its Bouncy value to 100%.
But wait! Don’t bounce on it yet, even though it’s very tempting. First, use the Bounce Pad to the left to proceed onto the overhead platform. Grab the Cow Head Sticker from the Prize Bubble, then jump off the platform onto the now-bouncy orange space below to leap forward onto the next platform. You’re going to have a ball!
Next up, work your way through a few challenges to progress through the level. Make the first wheel you see grabbable. Pop the Prize Bubble for the Bent Fork 1 Decoration as your sack person rides it around, grabs onto the sponge, and spins to the next platform above.
Make the next wall climbable, and collect the Bamboo Stick Decoration and Poster Paint Bottle Object as your sack person ascends.
Reduce the Friction of the ramp to lower the sponges and one of the Prize Bubbles (this one for the Chalk Arrow–Dotted Sticker). Increase the Friction and make it climbable so your sack person can climb along the outside of it, jump on top of it, and then run to the top to burst the other Prize Bubble for the Aubergine Object.
Line up the sponges to create a little staircase for your sack person to make it up the platform on the right. If you have a hard time moving the larger sponge, grab the smaller sponge from a distance and drag it hard, pressing both and 
simultaneously to put your sack person’s back into it, and hit the larger sponge on your way. This momentum can help the larger sponge budge an inch or two at a time.
Make the next platform bouncy—100% is good. Cross it and climb the net to the right, then jump off of it to bounce back toward the Prize Bubble hanging over the last Popit Powerup. Aim carefully, and you can collect the Subwoofer Object.
Next, make the large rotating orange wheel grabbable, then ride it around to pop the Prize Bubbles for the Laminated Desk–Trim Material and Margin Doodle 7 Sticker. Drop down at the bottom to proceed on your adventure.
Check out the Bounce Pad and tube, but don’t get too excited too quickly—there’s also a Prize Bubble waiting in the wings. Use the Bounce Pad to launch your sack person over the tube onto the platform. Now your sack person can gain some momentum to jump back onto the Bounce Pad and up toward the Prize Bubble for the Jewellery Decoration.
Time to move on with your lesson—and this one is fast! First, place a Material Tweaker on the orange platform below the tube and reduce its Friction to 0%, so it’s nice and slippery.
Now, use the Bounce Pad to slide down the tube, but don’t stop your sack person at the bottom. Let them keep sliding with grace and speed to the Bounce Pad at the end, and then hold for a big jump at that last beautiful second to reach the two Prize Bubbles hanging over the spikey gap. It’s a big chasm to leap over, but your little adventurer is a brave soul! Your rewards are the Some Kind of Object Sticker and Orange Cardboard Material, along with lots of fresh air in your sack person’s stitching.
To complete your lesson, you must collect a sponge and move it into position where outlined. See the sloping orange ramp on the left? Make it bouncy. See the larger orange platform in the middle? Give it friction. Now you have your sponge!
Push it into position, and use it as a stepping stool for your sack person. Grab ahold of the rotating sponge with , and swing around over the spikes to the other side.
Nice job! Looks like you learned a lot today.
