If the helmet were jammed head-down, you can use a needle-nose pliers to grasp the edge of the tube in the inside of the racing helmet, as shown, and then pull them apart. You may need to twist them apart as you pull. In your case, since the helmet is jammed head-up, you need a way to push it out from the bottom. I suggest drilling a small hole through ...
There's a brick-built spiral staircase in the Pet Shop: That's definitely the most common way to do it. You just build up around a central point. This can be expanded to use longer or wider steps: http://www.mocpages.com/moc.php/267772 You can also use 2x2 turntables if you need more strength and/or larger stairs: ...
Your second guess was correct. It's not just a wrench. It's listed as a Screwdriver/spanner on Lego.com: This part was also included in several sets in the Games line as a human tool to remove tiles from the dice. It's unclear (at least to me) whether this part was intended to be used for tile removal when it was introduced in 1979. Here's an example from ...
When your function (such as an extending crane boom) gets to one limit or the other, this clutch gear ratchets instead of binding up the motor and all the gears in between. ETA: Forgot the second question. It has appeared in many sets, most recently the Fairground Mixer.
The green parts are great to make a green smooth field, which is kinda obvious. Landscaping is one usage, and if you find it too uniform, don't forget you can cover some areas with additionnal hills or whatever. The Technic hole in there can come handy as you can easily attach something in it. Since it'll rotate freely, your added decoration can even be ...
Is it possible that you are thinking of this goblet (2343)? This part was fairly common, and it was introduced around 1985, so it was probably in your collection. 1x1 round plates attach securely to the top as shown in this lamp from the Pet Shop:
Technic Turntable Large Type 1 Base (2856). It's a Turntable Large Type 1 Top (2855) which is part of Technic Turntable Large Type 1, Complete Assembly (2856c01).
One possible solution might be to use one of the new 1x1 round plates with open studs and a Bar with Clip
Just today I tried to use it quite successfully as an alternative to suspension springs. Right now I don't have it assembled so I can't post a screenshot, but the idea is to wind up the pullback motor then attach it to your construction with a cross axis from one side and beams from another and limit its moving with some details. If you are interested in how ...
Using a cut-pipe into a clip-with-tube will let you build a secure and precise angle. If you have a solid brick behind the headlight bricks you can fix the angle by cutting the pipe at the right length.
Yoshihito Isogawa made clock mechanisms from it (well... tic-tac generators) http://www.isogawastudio.co.jp/legostudio/modelgallery_model/b077.html and http://www.isogawastudio.co.jp/legostudio/modelgallery_model/b078.html. Majorna created a "programmable" pull back racer http://www.eurobricks.com/forum/index.php?showtopic=69748&#entry1744425 ...and ...
In the case of 87609, the piece was first used in 2010 as part of the grill/bumper assembly for vehicles that were the standard 6 studs wide. Its length would appear to be a result of its original purpose. Its width also allows for attaching two rows of detail: 99206 showed up first in 2012. Its design allows for a more compact construction in ...
Short of damaging the parts (which oddTodd nicely documented, I'd tend to try to see if the part can't be removed by suction; although I'm not sure how you could generate enough. Trying to inject a fluid underneath (with sufficient pressure) might do the trick too; that's what doctors do when dealing with clogged ears (usually with a sort of big syringe). ...
I'm a noob and can only post two links, but check this out. And this modern classic uses a Duplo piece as a major element.
The minifigure stands make great commodes if you ever build a scene with a restroom.
Bricklinks information about Sports Minifig Stand, has information on where it's used in some sets that are not sports-related. For example: Viking Ship Troll Assault Wagon Troll Warship I don't own any of these sets, so I don't know exactly how this piece is used in there - maybe someone else can give information about that. The Sports Field Section 8 ...
buy a jolly rancher at your local gas station. screw in a long thin screw to a small portion of the jolly rancher, small enough to fit in the garbage can without touching any of the sides. wet the end of the jolly rancher and set it on the plastic helmet in the garbage can. wait a day for it to dry, then pull the helmet out, and soak it in water to ...
Build a catapult with it. The catapult arm would be attached to the motor. Pulling the arm down will wind the motor
Once I built a hand-powered semi-automated screwdriver toy for kids. They needed to "charge it" first by rotating a gear and then push a button to release power. Then they could apply it to a crane or other models.
A conditional can perhaps be represented by a door that can be blocked from the other side, or maybe two doors, of which only one is blocked via a sliding brick. As for loops, I would represent them as conditionals with counters, by blocking a door with a set number of bricks and removing one brick per iteration. If you'd rather count upwards, then a fixed ...
I still have cups and 1x1 round bricks from the late 70's and I can ensure you these were never brickable like you suggest. In the 80's, another popular build from Lego was composed of a transparent cup on top of a transparent minight head. Here is a colored example of that build.
You can also use heat to un-jam parts that have been tightly stuck with an air pocket between them, which sounds like it describes this situation. Running the parts under warm/hot tap water will cause the air to expand, pushing the pieces apart.
Thank you all for your answers. Now I must share the solution my 13 year old arrived at. I found two scratched elements and the pocketknife that pried them apart on my computer desk this morning. This was definitely NOT the best way to get a helmet out of a garbage can as both elements were damaged in the process, but the helmet (which now looks like it was ...
Besides the suggestions above another thing you might want to try is soapy water. Many times it will do the trick of separating elements stuck into each other.
I remember reading an article where someone stated that they used the Duplo 2x4 bricks to build up height for large models. The Duplo was then covered and surrounded by Lego, but that the Duplo added a lot of strength for the weight.
Generally, I would say that it's only the big, strangely shaped ones that have decent uses. Obviously you would very rarely use any of the small ones, and system is much better at this. (Only exception I can think of is a piece shortage (heaven forbid!)) I personally have never come across a MOC using DUPLO pieces in large scale, and I doubt you'll find a ...
